Abstract
Unsaturated polyesters are disclosed which are obtained from .alpha.,.beta.-unsaturated diacids of the cis form and polyols derived from polyhalogenated, polysubstituted polyphenyls. At the end of the esterification reaction, these polyesters possess from about 60 to 98% trans acid groups and from about 40 to 2% cis acid groups. The use of these polyesters in the preparation of various articles is also disclosed.
Claims1
