ABSTRACT:
A process for the production of glass-fiber reinforced plastics by partially copolymerizing a mixture of (A) 35-95% by weight methyl methacrylate, (B) 65-5% by weight of a vinyl aromatic hydrocarbon, and 0.2-5.0% by weight, based on the sum of (A) and (B) of a polymerizable compound containing two or more ethylenically unsaturated groups, discontinuing the partial copolymerization before gelation of said mixture has occurred, impregnating glass fibers with the resultant partially polymerized mixture and then curing the impregnated mixture.
