Polyisoprene-graft-maleic anhydride

• Catalog Number: ACM139948757-1
• Product Name: Polyisoprene-graft-maleic anhydride
• CAS: 139948-75-7
• Category: Biomaterials
• Description: Polyisoprene is strictly a general term for polymers produced by the polymerization of isoprene. In practice, polyisoprene is commonly used to refer to synthetic cis-1,4-polyisoprene made by the industrial polymerization of isoprene. Natural forms of polyisoprene are also used in large quantities, most importantly "natural rubber" (mainly cis-1,4-polyisoprene) extracted from tree sap. Both synthetic polyisoprene and natural rubber are highly elastic, so they can be used to make tires and a variety of other applications.
