ABSTRACT:
A polymerizable composition of matter comprises a cycloaliphatic epoxy resin, a cyanate ester resin, optionally a polyol, and, as initiator, a Bronsted acid. When cured, the compositions provide interpenetrating polymer networks (IPNs). The IPNs are useful as high temperature stable vibration damping materials, adhesives, binders for abrasives, and protective coatings.
