Abstract
A glass fiber-reinforced heat resistant resin composition which comprises: from 5 to 90% by weight of a pelletized polymer (A) obtained by suspension-polymerizing a vinyl aromatic monomer optionally together with an unsaturated nitrile monomer and a vinyl monomer copolymerizable therewith, in the presence of chopped glass fiber strands, and comprising from 50 to 90% by weight of the chopped glass fiber strands and from 50 to 10% by weight of a resin component consisting essentially of from 40 to 100% of residues of the vinyl aromatic monomer, from 0 to 60% of residues of the unsaturated nitrile monomer and from 0 to 30% of residues of the copolymerizable vinyl monomer; from 95 to 10% by weight of a polymer (B) comprising from 10 to 50% of residues of a maleimide monomer, from 90 to 50% of residues of a vinyl aromatic monomer, from 0 to 10% of residues of maleic anhydride and from 0 to 30% of residues of a vinyl monomer copolymerizable therewith.
