摘要： Vulcanizates with desirable properties can be obtained from compounds incorporating polymers that include hydroxyl group-containing aryl functionalities. The functionalities can be incorporated by using any or all of appropriate initiators, monomers and terminating compounds. Such polymers exhibit excellent interactivity with both conventional and non-conventional fillers.

摘要： Metallic complexes having indenyl ligands can be used as an ingredient of a catalyst system. The catalyst system can be used in polymerizations of ethylenically unsaturated hydrocarbon monomers that include both olefins and polyenes. Embodiments of the catalyst system can provide interpolymers that include polyene mer and from 40 to 75 mole percent ethylene mer, with a plurality of the ethylene mer being randomly distributed. The catalyst system also can be used in solution polymerizations conducted in C5-C12 alkanes, yielding interpolymers that include at least 10 mole percent ethylene mer.

摘要： Disclosed herein are solution polymerization processes for producing a high-cis polydiene. The processes include polymerizing at least one conjugated diene monomer in an organic solvent in the presence of at least one thiol compound and a lanthanide-based catalyst composition to produce a polydiene having a cis-1,4-linkage content of 90-99%. The at least one thiol compound is represented by the general formula R—S—H, where R is a hydrocarbyl group or a substituted hydrocarbyl group. The lanthanide-based catalyst composition comprises (a) a lanthanide compound, (b) an alkylating agent, and (c) a halogen source, where (c) may optionally be provided by (a), (b), or both (a) and (b). The molar ratio of the at least one thiol compound to the lanthanide compound used in the polymerization process ranges from 0.01:1 to 100:1. Improved solution polymerization processes regarding the same are also disclosed herein.

摘要： A method for providing a polymer having terminal functionality involves reacting a terminally active polymer with an α,β-ethylenically unsaturated compound that includes a group 2-13 element so as to provide a functionalized polymer. The resulting polymer exhibits enhanced interactivity with particulate fillers and can be used in the manufacture of vulcanizates.
