Curable molding compositions containing a poly(acrylate)

摘要

Described herein are curable molding compositions comprising a mixture of: (a) a poly(acrylate) characterized by the following empirical formula: <IMAGE> (I) wherein R is the hydroxy-free residue of an organic polyhydric alcohol which contained alcoholic hydroxyl groups bonded to different carbon atoms, R1 and R2 are independently hydrogen or methyl, and n is 1 to 3, (b) acrylic or methacrylic acid or a functionalized derivative thereof having a molecular weight of less than 300 which is different from (a), and (c) an ethylenically unsaturated monomer which is soluble in and copolymerizable with (a) and (b) and which is different from (a) and (b). The compositions can also contain one or more fibers with a melting point or a glass transition temperature above about 130 DEG C.
