    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 alicyclic 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： Bis(1,3-dienyl)dialkyltin, lead, and germanium compounds employed in the aqueous emulsion polymerization of conjugated dienes, optionally with vinyl comonomers, provide polymers with sufficiently high Mooney viscosity values as to be readily handled in plant operations, yet which exhibit controlled breakdown under milling to lower Mooney values suitable, for a variety of uses.

    摘要： A highly dispersed emulsion of an organosulfur compound is obtained by use of a coemulsification system of a surfactant, and an electrolyte, and a cosurfactant and optionally a hydrocarbon; such as a petroleum sulfonate with potassium chloride and hexyl alcohol. Conversion of organosulfur compounds into highly dispersed emulsions increases the reactivity of the organosulfur compound as a molecular weight modifier in an aqueous emulsion polymerization system and permits the efficient use of high molecular weight organosulfur compounds.
