摘要： This invention relates to a process for making a coupled block copolymer composition, comprising the steps of. a. reacting a living lithium-terminated polymer having the formula P-Li, where P is a copolymer chain having at least one polymer block A composed of one or more mono alkenyl arenes having 8 to 18 carbon atoms and at least one polymer block B composed of one or more conjugated dienes having 4 to 12 carbon atoms, with an alkoxy silane coupling agent having the formula R-Si-(OR') 3 , where R is selected from aryl radicals having from 6 to 12 carbon atoms, or linear alkyl and branched alkyl radicals having from 1 to 12 carbon atoms, and R' is selected from linear alkyl radicals having from 1 to 4 carbon atoms, and where the molar ratio of Si to Li is between 0.35 and 0.7, thereby forming a coupled block copolymer composition; b. optionally hydrogenating the coupled block copolymer composition; and c. recovering the resulting coupled block copolymer composition. It also relates to the resulting composition.
