摘要: A gel profile article comprising a multi-filament yarn carrier carrying an elongate body of gel which encloses more than 50%, preferably more than 75%, more preferably substantially all, of the perimeter of the carrier as viewed in transverse cross-section, wherein the carrier is at least partly composed of synthetic polymeric material, preferably polyester filaments (e.g. polyethylene terephthalate) or spun yarns of a co-mingled blend of polyacrylonitrile staple fibres and polyamide staple fibres ("baby wool"), the proportion of polyamide preferably being at least 30%, more preferably 40-60%, by weight of the said spun yarn(s). The gel is preferably melt-coated, especially pressure-extruded, around the carrier at a gel temperature less than the softening temperature of at least a component of the carrier, and the selected class of carrier materials enhances the processability, cohesion, and appearance of the resulting profile.

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.
