Post-functionalization of novolac resins by introducing thermo-crosslinkable –OCFCF2 groups as the side chains: a new strategy for production of thermosetting polymers without releasing volatiles

Abstract

Post-functionalization of a commercial novolac resin by introducing thermo-crosslinkable trifluorovinylether groups as the side chains offers a new polymer, which can form a cross-linked network without releasing volatiles during thermal curing. The cured resin shows a lower dielectric constant and higher thermostability than those of most commercial novolac resins.
