    摘要： A specialized polymeric peroxide is copolymerized with vinyl type monomers in the presence of organic liquid, thereby obtaining a solution of a copolymer having peroxy bonds therein.This solution is admixed with vinyl type monomers which are different in composition from the ones used in the first copolymerization, and the resultant mixture is subjected to block copolymerization.The obtained block copolymer solution is admixed with an organic liquid which exert solubility to one of polymers of the vinyl type monomers which are employed in the first or second copolymerization, whereby a non aqueous system liquid dispersion is obtained.This dispersion contains a block copolymer in a high concentration and it also is splendid in uniformity of dispersion and dispersion stability.

    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, a thermoplastic polymer low profile additive, and a free radical initiator mixture containing at least one initiator with a 10-hour half-life temperature (t.sub.1/2) of greater than about 90.degree. C. and at least one initiator with a 10-hour half-life temperature (t.sub.1/2) of less than about 90.degree. C. 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.
