摘要： M-A-M triblock copolymers of higher alkyl (especially isobornyl) methacrylates, potentially for forming gels of improved temperature rating over PMMA triblock gels, are synthesized by anionic polymerization of an alkylene (pref. butadiene or isoprene) mid-block (A) followed by anionic polymerization of the methacrylate end blocks (M) using alkali metal alkyl initiators. Mixed end blocks (M) comprising random or block copolymers of methylmethacrylate and one or more higher alkyl (pref. isobornyl) methacrylates are preferred for forming gels with elevated softening temperatures without loss of structure which apparently tends to occur with IBMA homopolymer ends blocks.

摘要： Gels of oil-extended methacrylate-alkylene-methacrylate (M-A-M) triblock copolymers having higher glass transition temperatures than known styrene-alkylene-styrene triblock gels. The preferred M-A-M triblocks for making the new gels have polymethylmethacrylate end blocks and butadiene or ethylene/butylene mid-block, and are synthesised by methods in the public domain (inter alia Shell EP-A-0431706). Includes gels of new triblocks having end blocks of higher alkyl (e.g. isobornyl) methacrylate homopolymer or copolymers. Mixed methyl- and higher alkyl- methacrylate end blocks are preferred to reduce gel-formation problems which may arise from solubility parameter of homo-isobornylmethacrylate end blocks being too close to that of extender oil. Includes gels of new multi- (preferably penta-) block copolymers including styrene (S) blocks, e.g. M-S-A-S-M.
