In a thermosetting composition containing high vinyl alkadiene polymer, organic peroxide, calcium carbonate filler and optional ingredients comprising a vinyl arene liquid monomer, coupling agent, polymerizable plasticizer, and fiberglass reinforcing filler, the addition of an adduct of polybutadiene and a carboxylic acid anhydride improves properties of the molded compositions comprising flexural modulus, tensile strength and Barcol hardness.
