ABSTRACT:
A process for producing a halogen-containing unsaturated polyester which comprises halogenating a dicyclopentadiene-terminated unsaturated polyester by feeding the unsaturated polyester into a reaction system which contains halogen. The unsaturated polyester or a resin composition containing the same shows a by far improved color tone, as compared with conventional ones, and also exhibits an increased halogen content and an elevated deflection temperature. They can be advantageously used as raw materials in every industrial fields, such as electrical appliances, construction materials, automobiles, railroad wagons and airplanes.
