ABSTRACT:
Molded articles comprising glass fiber reinforced styrene polymer wherein the weight ratio of glass fiber to styrene polymer is in the range of about 55:45 to about 75:25. The molded articles are prepared by a transfer molding process in which glass fiber mat containing 1 to 5 weight percent of an unsaturated polyester binder is impregnated with styrene monomer and the mold is subjected to conditions which induce fast polymerization of the styrene monomer. The molded articles possess resistance to heat distortion.
