Abstract

Novel polymerizable multivinylaminosilanes which are useful as branching agents for synthetic and natural rubber are described. The compounds can be used in the polymerization of conjugated diene monomers, optionally together with aromatic vinyl monomers, thus producing polymers, which can favorably be used in rubber articles such as tires.
