Application of 2-Methyl-4,6-Bis(Octylsulfanylmethyl)Phenol as Antioxidant in Polybutadiene Polymerization
Kozak, Radosław, et al. International Journal of Polymer Analysis and Characterization, 2015, 20(7), 602-611.
A study explored the effect of Lewis base (σ complex) amine ether-type and ether-type polar modifiers on the microstructure of anionically polymerized polybutadiene. The strongest and comparable influence on 1,2 butadiene isomeric structure formation was provided by DMEAEE > DTP > THF-DEA. In this work, 2-Methyl-4,6-bis(octylsulfanylmethyl)phenol (Irganox 1520) was used as an antioxidant. Polymerization of polybutadiene · Three amine-ethers, DMEAEE, THF-DEA, and DMDEE, along with two ethers, ETE and DTP, were utilized as polar modifiers in the anionic polymerization of 1,3-butadiene. · The impact of varying polar modifier concentrations in nonpolar solvents on polybutadiene microstructure was investigated through anionic polymerizations carried out in individual glass bottles using a custom bottle polymerizer. · All reactions were conducted for 2 hours at a constant temperature of 70°C to ensure consistency in polybutadiene microstructure. Following the reaction, it was stopped with 0.5 mL of 2-propanol and an antioxidant (Irganox 1520) was added. · The polymer solutions were then left overnight under a fume hood for solvent evaporation and subsequently dried in a vacuum dryer at 65°C and 10 mbar for the next 12 hours.
4,6-Bis (octylthiomethyl)-o-cresol as Antioxidant in Emulsion Polymerization of Isoprene
Minari, Roque J., et al. Journal of applied polymer science, 2010, 116(1), 590-601.
Polyisoprene (PI) can be prepared by batch seed-free emulsion polymerization of isoprene using n-dodecyl mercaptan as a chain transfer agent (CTA). In this work, three batch emulsion polymerizations of Is at 10 C were carried out, and a global polymerization model was adjusted to measurements of monomer conversion, particle diameter, and average molecular weights. During the synthesis process, 4,6-bis (octylthiomethyl)-o-cresol is used as an antioxidant to avoid latex degradation. Polymerizations and characterization · Initially, the emulsifier and 390 g of water were placed in the reactor. The temperature was then set to 10 °C, following which the monomer, CTA, and initiator were added, and the mixture was stirred for 30 min with continuous N2 bubbling. Polymerization began when a water solution of FeSO4.7H2O, SFS, and EDTA was introduced. · Each latex sample was divided into three fractions. The first fraction was dried at 80 °C until a constant weight was achieved to measure conversion. The second fraction was diluted with water for particle size measurement. The third fraction underwent SEC characterization as follows: (a) an antioxidant [4,6-bis (octylthiomethyl)-o-cresol] was added to the latex to prevent degradation; (b) the latex was precipitated in isopropanol; and (c) the precipitate was filtered, dried under vacuum, and stored in the dark at 15 °C for analysis.
