Abstract: Alkali metal aliphatic and aromatic hydrocarbon acetals and ketals are initiators for the polymerization of conjugated dienes and copolymerization of conjugated diene and vinyl monomers. Mono-acetal and mono-ketal polymers are produced by termination of the foregoing polymers and copolymers with methanol, isopropanol, etc.; diacetal and diketal polymers are produced by terminating said polymers and copolymers with a joining agent, e.g. Cl.sub.2 Si(CH.sub.3).sub.2 ; and polyacetal and polyketal polymers and copolymers are produced by terminating said polymers and copolymers with a polyfunctional joining agent, e.g. Cl.sub.3 SiCH.sub.3. Other mono-acetal and mono-ketal polymers are prepared by terminating said polymers and copolymers with ethylene oxide or carbon dioxide. The terminally reactive acetal polymers can be converted to other useful polymeric products.

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.

Abstract: The molecular weight of a liquid, linear dead polymer terminated with an alpha-alkoxyalkyl ether group, is increased by heating with an acid catalyst in the absence of a solvent.
