ABSTRACT:
A flame-retardant, unsaturated polyester resin composition comprising a halogen-containing unsaturated polyester obtained by halogenating an unsaturated polyester prepared by the reaction of (a) dicyclopentadiene, (b) .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid or its anhydride, (c) tetrahydrophthalic acid or its anhydride and (d) polyhydric alcohol.
Crosslinked products of the composition exhibit increased halogen content and elevated deflection temperature, and are particularly useful for electric appliances, building materials, automobiles, railroad wagons, airplanes, etc.
