CA 2213333

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 can provide interpenetrating polymer networks (IPNs). The IPNs are useful as high temperature stable vibration damping materials, adhesives, binders for abrasives, and protective coatings.

Composition polymérisable renfermant une résine d'époxyde cycloaliphatique, une résine d'ester de type cyanate, facultativement un polyol et, comme initiateur, un acide de Bronsted. Après réticulation, les compositions peuvent former des réseaux polymériques interpénétrants, utiles comme adhésifs, liants pour abrasifs, revêtements protecteurs et amortisseurs de vibrations thermostables.
