ABSTRACT:
This invention comprises a polymerizable composition of a liquid mixture of (a) an unsaturated polyester, (b) a half ester characterized by the following empirical formula: ##STR1## wherein n is a number having an average value of about 1.5 to less than about 4, m is equal to the free valence of A less the average value of n, A is the hydroxyl-free residue of an organic polyol which contained from 2 to 4, inclusive, hydroxyl groups, OH, in formula (I), (c) maleic anhydride and (d) an ethylenically unsaturated monomer. This composition is suitable for use in the manufacture of fiber reinforced plastic compositions.
