- 1. A reinforcing agent coated with a graft copolymer comprising a backbone polymer having a hydrocarbon chain portion and a plurality of pendant hydrocarbon groups each containing a moiety of the formula: ##STR8## wherein R.sup.a and R.sup.b are independently selected from the group consisting of hydrogen and alkyl of from 1 to 16 inclusive carbon atoms, having grafted thereon an acrylate of the formula: ##STR9## wherein R.sup.c is selected from the group consisting of hydrogen and alkyl of from 1 to 3 inclusive carbon atoms and R.sub.d is alkyl of from 1 to 30 inclusive carbon atoms, to form a graft copolymer, wherein the said backbone polymer is 1,2-polybutadiene and wherein about 5 to about 80 percent by weight of the graft copolymer is 1,2-polybutadiene with the balance being the said acrylate, and wherein the said reinforcing agent is selected from the group consisting of glass fiber, asbestos fiber and alpha-cellulose.
- 2. The composition of claim 1 wherein the reinforcing agent is glass fiber.
