Abstract
Disclosed is an unsaturated polyester containing formal linkages. The polyester is comprised of the following repeating unit ##STR1## wherein X is a positive integer from 2 to 10, R is the divalent radical remaining after removal of the terminal carboxyl group from an .alpha.,.beta.-ethylenically unsaturated dicarboxylic acid, and R' is the divalent radical remaining after removal of the terminal hydroxyl groups from an aliphatic or cycloaliphatic glycol. The polyesters of this invention exhibit a combination of a desirable hardness and a desirable impact strength upon curing.
