Abstract
PURPOSE: The titled one-component composition having low cure shrinkage, consisting of (A) a copolymer of vinyl acetate and an alkyl acrylate, (B) an unsaturated polyester and (C) an unsaturated monomer copolymerizable with component B.
CONSTITUTION: The purpose composition is obtained from the following three components: (A) a copolymer (MW of 10,000W100,000 is preferred) of vinyl acetate and an alkyl methacrylate or alkyl acrylate (e.g., methyl methacrylate) (present in the copolymer in 5W50wt%), (B) an unsaturated polyester (prepared from a material comprising an unsaturated polycarboxylic acid, a saturated carboxylic acid, a polyalcohol, etc.) and (C) an unsaturated monomer copolymerizable with the unsaturated polyester (e.g., a monomer which can uniformly dissolve components A and B, such as styrene). The mixing proportion of copolymer as component A is preferably 3W9wt%.
