Polymerizable unsaturated polyester compositions useful in the manufacture of multilayer laminates and laminates prepared therefrom

Abstract From the Canadian patent

Polymerizable unsaturated polyester compositions are provided particularly useful in the manufacture of multilayer laminates consist-, ing essentially of, (1) a polyester of a polyhydric alcohol and a polycarboxylic acid, at least one of which is ethylenically unsaturated; (2) a monomer copolymerizable with the unsaturated polyester and having a boiling point below 150°C; (3) an additive forming a film on the polyester surface that inhibits volatilization of monomer form the polyester composition; and (4) a hydrophobic compound soluble at least in part both in the unsaturated polyester and in the film-forming additive that either (a) has an isoprene unit structure, or (b) is acyclic and has …
