Abstract: There are disclosed novel, solid, elastomeric block copolymers with improved resistance to cold flow wherein either 1) the terminal blocks are polymers of at least one conjugated diene I, e.g., isoprene, which contains at least five carbon atoms with at least one of each pair of double-bonded carbon atoms in the polymerized diene I units being additionally single-bonded to two carbon atoms, at least one middle or interior block is a polymer of butadiene, and at least one middle or interior block is a polymer of at least one aryl-substituted olefin, e.g., styrene; or 2) the terminal blocks are random copolymers of at least one diene I as previously defined and butadiene, and at least one middle or interior block is a polymer of at least one aryl-substituted olefin. The invention also encompasses the selective hydrogenation of the foregoing polymers such that substantially all of the residual double bonds of the polymerized butadiene units are hydrogenated while a sufficient number of polymerized I units remain unsaturated to provide a basis for subsequent vulcanization or cross-linking.

Abstract: There is disclosed a highly selective hydrogenation catalyst composition synthesized by adding an organometallic reducing agent, e.g., triethylaluminum, to a transition metal compound, e.g., nickel (II) octoate. The catalyst composition is synthesized either by adding the organometallic reducing agent to the transition metal compound, in that order, as rapidly as possible, or by adding the reducing agent and the transition metal compound, separately but substantially simultaneously, at substantially constant molar ratios to the catalyst synthesis vessel. The catalyst composition is subtantially more selective in hydrogenating mono-substituted and symmetrically disubstituted polymer double bonds in the presence of unsymmetrically disubstituted double bonds and double bonds having three or more substituents, and substantially more stable over extended periods of time at ambient conditions than prior art catalysts.

Abstract: There is disclosed a linear block copolymer comprising at least one triblock I-B-I, wherein I is a block of at least one polymerized conjugated diene of at least five (5) carbon atoms, such as isoprene, and B is a block of a polymer of at least one conjugated diene, different from that used to polymerize the block I, of at least four (4) carbon atoms, such as 1,3-butadiene. The B block is selectively hydrogenated, while each of the I blocks is hydrogenated and therefore retains a sufficient amount of its original unsaturation to vulcanize the copolymer. There is also disclosed an alternative linear block copolymer containing at least one triblock of the first polymer block made from a minor proportion of at least one aryl-substituted olefin, such as styrene, and a major proportion of at least one conjugated diene used to polymerize the block I, the second middle polymer block of at least one diene used to polymerize the block B, and the third polymer block which is the same as the first polymer block. In this alternative copolymer, the middle block is also selectively hydrogenated, thereby leaving the terminal polymer blocks with a sufficient amount of their original unsaturation to vulcanize the copolymer. The polymers can be crosslinked or functionalized through the terminal blocks containing the vinyl unsaturation. There are also disclosed random linear and star-branched block and random copolymers made from the same monomers as the linear block copolymers. Also disclosed are methods of producing the polymers and selectively hydrogenating the aforementioned polymerized dienes.

Abstract: The invention provides dispersants and dispersant viscosity index improvers which include polymers of conjugated dienes which have been hydrogenated, functionalized, optionally modified, and post treated. The dispersant substances include a copolymer of two different conjugated dienes, such as butadiene-isoprene-butadiene. The polymers are selectively hydrogenated to produce polymers which have highly controlled amounts of unsaturation, permitting highly selective functionalization. Also provided are lubricant fluids, such as mineral and synthetic oils, which have been modified in thei r dispersancy and/or viscometric properties by means of the dispersant substances of the invention. Also provided are methods of modifying the dispersancy and/or viscometric properties of lubricating fluids such as mineral and synthetic lubricating oils. The dispersant substances may also include a carrier fluid to provide dispersant concentrates.
