Title:
IMPROVED LOW SHRINKAGE CURABLE POLY(ACRYLATE) FORMING COMPOSITION
Document Type and Number:
Japanese Patent JPS6018507
Kind Code:
A
Abstract:
This invention is directed to curable molding compositions containing a mixture of a poly(acrylate); a polymerizable ethylenically unsaturated monomer which serves to crosslink the poly(acrylate) to a thermoset product; at least one of the following: (i) one or more crosslinkable vinyl monomers having a reactivity ratio (r1) with styrene of greater than one, (ii) an epoxy compound having at least one 1.2-epoxy group per molecule, and (iii) an unsaturated fatty acid ester; and a thermoplastic polymer low profile additive. The curable molding compositions exhibit improved shrink control during the curing reaction. This invention is also directed to fiber reinforced thermoset resin articles which exhibit generally improved surface appearance quality and can be produced by a rapid injection molding process from the curable molding compositions.
