A non-functional liquid rubber is prepared by the solution polymerization of vinyl monomers. The polymer may be a homopolymer or a copolymer. As a copolymer the preferred monomers are a conjugated diene and a vinyl substituted nitrile such as acrylonitrile or methacrylonitrile. A non-functional initiator is employed that is either an azo initiator or a peroxide initiator.
