Case Study

Evaluation of glycerol propoxylate triglycidyl ether for the synthesis of reactive diluents

Liu, Fang, et al.Journal of Biomaterials Science, Polymer Edition 22.10 (2011): 1379-1391.

A new methacrylate triester oligomer GPTEMA with three long-chain branches was synthesized by the reaction of glycerol propoxylate triglycidyl ether (GPTE) and methacrylic acid. The structure of GPTEMA was confirmed by FT-IR, H-NMR, gel permeation chromatography (GPC) and elemental analysis. The results showed that Bis-GMA/TEGDMA/GPTEMA copolymers obtained lower polymerization shrinkage and higher double bond conversion. However, its T, flexural strength and flexural modulus decreased with the increase of GPTEMA content, and the water adsorption and diffusion coefficient increased with the increase of GPTEMA content.
A mixture of 12.0 g glycerol propoxylate triglycidyl ether (GPTE), 12.9 g methacrylic acid, 0.12 g N,N-dimethylbenzylamine and 0.01 g hydroquinone was added to a 100 ml three-necked round-bottom flask equipped with a nitrogen inlet adapter. The reaction mixture was stirred and heated to 90°C and then kept at this temperature for 9 hours. The reaction process was monitored by FT-IR until the epoxy absorption peak at 910 cm completely disappeared. After the reaction was completed, the mixture was diluted with 50 ml dichloromethane. The mixture was extracted with 3% aqueous HCl solution to remove the catalyst and 3% aqueous NaOH solution to remove excess acid. The mixture solution was then washed with brine until the pH value of the aqueous phase reached about 7.0. The organic phase was collected and dried over anhydrous magnesium sulfate overnight. After filtering to remove the desiccant, the organic phase was rotary evaporated under reduced pressure at 60°C. The crude product was dried under hard vacuum to remove any residual solvent, and then GPTEMA was obtained as a yellow viscous liquid (11.0 g, 79.6% yield).

Evaluation of dielectric and mechanical relaxation of glycerol propoxylate triglycidyl ether

Paluch, Marian. Journal of Physics: Condensed Matter 12.45 (2000): 9511.

The dielectric relaxation behavior of a three-armed star molecule of glycerol propoxylate triglycidyl ether (EP3) and a low molecular weight linear polymer poly(propylene glycol)-bis(2,3-epoxypropyl ether) (EP2) were compared. It is also interesting to investigate how the topological differences of these epoxy resins affect the dynamics of the α relaxation process. In addition to the α mode, an additional relaxation process was observed in the dielectric spectrum of EP3, which is visible only in the high temperature range. In order to understand the nature of this additional mode, mechanical measurements were also performed over the widest possible frequency range. In addition, the effect of high pressure on the dielectric relaxation behavior in EP3 was investigated.
Dynamic mechanical measurements were performed by rheometric mechanical spectroscopy. Shear deformation was applied under conditions of controlled deformation amplitude, always kept within the linear viscoelastic response of the investigated glycerol propoxylate triglycidyl ether. The frequency dependence of the storage (G) and loss (G) shear moduli were measured at different temperatures. A parallel plate geometry was used below 25 °C with a plate diameter of 6 mm. In the case of the plate-plate geometry, the gap between the plates (sample thickness) was approximately 1 mm. The experiments were performed under a dry nitrogen atmosphere.

Glycerol propoxylate triglycidyl ether participates in the preparation of adhesives

Sun, Changjiang, et al. ACS omega 9.21 (2024): 22703-22710.

In order to solve the problem of formaldehyde release in engineering wood adhesives and improve the waterproof, fireproof and mildew-proof properties of adhesives, a new type of environmentally friendly biomass-based adhesive was developed. The study carboxymethylated kraft paper lignin and then blended it with adhesives made of Glycerol propoxylate triglycidyl ether and soy protein isolate (SPI). The dry and wet shear strength of the resulting adhesive plywood was improved. Carboxymethyl lignin (CML) significantly improved the mildew resistance and flame retardant residual rate of the adhesive and reduced the water absorption rate from 190% to 108%. In addition, the adhesive showed excellent flame retardancy and self-extinguishing properties, which is suitable for industrial production.
Kraft paper lignin or CML was added to 42 g of distilled water. The pH value was adjusted to 9 using 10 wt % NaOH solution, the mixture was fully stirred, and then soy protein (10 g) was added under vigorous stirring. Then different cross-linking agents such as Glycerol propoxylate triglycidyl ether were introduced and the mixture was stirred at 1200 rpm for 10 min. The adhesives were called SPI-#lig or SPI-#CML, where # represents the weight percentage of lignin or CML based on the weight of SPI, respectively.

Glycerol propoxylate triglycidyl ether participates in the preparation of superoleophilic amphibious fabrics

Fu, Sida, et al. Materials Horizons 6.1 (2019): 122-129.

Most superoleophilic surfaces reported so far show oleophobic properties in underwater environments. It remains challenging to develop superhydrophilic surfaces that simultaneously show superhydrophilicity and underwater superoleophilicity. A new strategy can prepare surfaces that are simultaneously superamphiphobic in both air and underwater environments. A cross-linkable polymer material composed of hydrophilic and oleophilic functional groups was coated onto a fabric substrate using a single-step glycerol propoxylate triglycidyl ether coating method. The coated fabrics exhibited amphibious superphilicity with a contact angle of 0° for both water and oil. In the dry state, water and oil fluids with surface tensions in the range of 18.4-50.8 mN m-1 completely diffused onto the surface in less than 1 second. In water, although the fabric was wetted quickly, it still allowed the oil to completely diffuse into the wetted fabric matrix in less than 1 minute. More interestingly, the underwater superoleophilicity was self-healable to chemical damage. It is further shown that this amphibious superoleophilicity has great potential for oil recovery from water.
To prepare the amphibious superoleophilic fabric, woven polyester fabric was used as the substrate and the coating was carried out using a dip coating technique. The coating solution was prepared by mixing glyceryl triglycidyl ether (GPTE) with octadecylamine (ODA) in ethanol. GPTE can react with ODA via an epoxide-amino coupling reaction. After the reaction was completed, the solution looked transparent. It was very stable under ambient conditions. After being stored at room temperature for one month, the solution was still very transparent with no precipitation.
