A method of chemically cross-linking sterically hindered epoxidized polymers

摘要

This invention is a method of curing epoxidized diene polymers which do not have a significant amount of functional groups which undergo a cross-linking reaction with amino resins and which have at least 50 olefinic epoxy groups which are predominately sterically hindered and which comprise at least one conjugated diolefin monomer, said method comprising mixing said polymer with an amino resin in the presence of a proton-donating acid catalyst.
