ABSTRACT OF THE DISCLOSURE Described herein are curable molding com- positions comprising a mixture of: (a) a half ester of an organic polyol characterized by the following empirical formula: (I) Image 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 R less the average value of n, and R is the hydroxyl- free residue of an organic polyol which contained from 2 to 4, inclusive, hydroxyl groups in formula (I), (b) maleic anhydride, (c) acrylic or methacrylic acid or a func- tionalized derivative thereof having a molecular weight of less than 300, and (d) an ethylenically unsaturated monomer which is soluble in and copolymerizable with (a), (b), and (c) and which is different from (a), (b), and (c). The compositions can also contain one or more fibers with a melting point or a glass transition temperature above about 130°C.
