    摘要: Alicyclic organomonolithium compounds having delocalized conjugated unsaturation are effective initiators in the preparation of polymers of conjugated dienes. Polymers of conjugated dienes, prepared with or without the alicyclic organomonolithium compounds, are terminated with alicyclic compounds having conjugated unsaturation. Either or both approaches can be used to provide polymers containing alicylic conjugated unsaturated functional groups. Alternatively, polymers prepared from the alicyclic organomonolithium compounds can be coupled to produce linear or branched polymers. Polymers prepared from multichelic lithium compounds also can be terminated with alicyclic conjugated unsaturated compounds.

    摘要: Organosulfur molecular weight regulators for emulsion polymerization systems, such as mercaptan compounds, are mixed and agitated with the aqueous emulsifier prior to use in emulsion polymerization systems. The modifying efficiency of the organosulfur molecular weight modifiers can be controlled by the degree of agitation. In many cases, adding the agitated mixture incrementally to the emulsion polymerization system further improves effectiveness of the modifier.

    摘要: Solution polymerized rubbery conjugated diene homopolymers and copolymers with monovinylarenes are terminated with a hydrocarbyl phosphite or thiophosphite. The phosphite terminated polymers, particularly medium-vinyl polybutadiene, can be incorporated in rubber/carbon black/oil tread stock compounds employing up to 65 parts of rubber per 100 parts of polymer and up to 30 parts of oil per 100 parts of polymer for higher resilience, lower hysteresis, and generally higher tensile strength after vulcanization.
