ABSTRACT:
This invention is a method of curing unsaturated polymers which do not have a significant amount of functional groups which undergo a crosslinking reaction with amino resins and which preferably 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.
