PHYSICALLY CROSSLINKABLE COMPOSITION

Described is a polymerizable composition comprising (meth)acrylate ester monomer, a macromer and a polymerizable Norrish type I, photoinitiator. The resulting copolymers are physically crosslinked and generally those copolymers having greater than 20 percent macromer produce optically clear films an...

Zusammenfassung:Described is a polymerizable composition comprising (meth)acrylate ester monomer, a macromer and a polymerizable Norrish type I, photoinitiator. The resulting copolymers are physically crosslinked and generally those copolymers having greater than 20 percent macromer produce optically clear films and those having less than 20% macromer can provide high performance pressure sensitive adhesives.
