<p>Polymerizable unsaturated polyester compositions are provided, particularly useful in the manufacture of multilayer laminates, consisting 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.degree.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 at least one ester and/or ether bond; and at least two terminal hydrocarbon groups, each with at least one ethylenically unsaturated group.</p> |
