ABSTRACT:
N,N-bis(trialkylsilyl) amino-terminated polymers are prepared by treating p-lithio-N,N-bis(trialkylsilyl) aryl amine with a diene monomer and the resulting polymers are converted to a mono- or di- primary aryl amine-ended diene polymer directly by acid hydrolysis. The amine-ended polymers may be homopolymers of a conjugated diene which contain 4 to 8 carbon atoms or copolymers of such conjugated dienes or copolymers of such a conjugated diene and a vinyl monomer.
