Curable poly(acrylate) molding compositions containing a thermoplastic
polymer low profile additive
摘要:
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, unsubstituted or substituted meta- and/or para-divinylbenzene 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.
