摘要： Metal salts of cyclic alcohols can be used as modifiers in lithium initiated solution polymerizations of diene monomers into rubbery polymers having a low vinyl content. For instance, such initiator systems can be used in the copolymerization of styrene and isoprene to produce low vinyl styrene-isoprene rubber having a random distribution of repeat units that are derived from styrene. It is important for such polymerizations to be conducted in the absence of polar modifiers, such as Lewis bases. The subject invention more specifically discloses an initiator system which is comprised of (a) a lithium initiator and (b) a metal salt of a cyclic alcohol, wherein said initiator system is void of polar modifiers. The present invention also discloses a process for preparing a rubbery polymer having a low vinyl content which comprises: polymerizing at least one diene monomer with a lithium initiator at a temperature which is within the range of about 5° C. to about 100° C. in the presence of a metal salt of a cyclic alcohol, wherein the molar ratio of the metal salt of the cyclic alcohol to the lithium initiator is within the range of about 0.05:1 to about 10:1, and wherein the process is conducted in the absence of polar modifiers.

摘要： The process and catalyst of this invention can be utilized to synthesize homo and copolymers of conjugated diene monomers and vinyl aromatic monomers having high trans contents of greater than 60% with low melting points. These homo and copolymers of conjugated diene monomers and vinyl aromatic monomers can be utilized in tire tread and sidewall rubbers that exhibit outstanding wear and tear characteristics in the tread and excellent flexing properties in the sidewall. The rubber polymers of this invention are made utilizing an improved catalyst system. This catalyst system is comprised of (a) organo aluminum compounds, (b) organo lithium compounds, (c) a barium compound selected from barium salts of (i) di(ethylene glycol) ethyl ether, (ii) di(ethylene glycol) propyl ether, (iii) di(ethylene glycol) hexyl ether, (iv) di(N,N-dimethyl amino glycol) ethyl ether, (v) menthol and thymol in the presence of polar modifier consisting of water, alcohols, amines, thiols, phosphates and phosphites. The trans polymers and copolymers of this invention made with the above catalyst system typically have a glass transition temperature ranging from −97° C. to −40° C., a melt temperature ranging from −30° C. to +30° C., and a number average molecular weight from 20,000 to 250,000. The inclusion of such polar modifiers in the barium catalyst system results in a high styrene content in copolymerization, a high trans content, and high molecular weight. Copolymers of conjugated diolefin monomers and vinyl aromatic monomers made with the catalyst system of this invention also have a tapered macrostructure.
