    摘要: The present invention relates to pressure sensitive adhesive compositions prepared from novel anionic block copolymers of aromatic vinyl compounds and conjugated dienes. The block copolymers are a mixture of a high molecular weight linear and/or radial block copolymer component (SBC1 and/or SBC2), and a diblock copolymer component (D1). The block copolymer may be combined with other block copolymers, tackifying resins, oils and other components to form the adhesives of the present invention. The pressure sensitive adhesives of the present invention maintain their performance at elevated temperatures and fail cohesively making them particularly useful for die-cuttable label applications. The pressure sensitive adhesives compositions may also comprise ester plasticizers typically used for PVC and thus make adhesives particularly suitable for PVC film labels and decals.

    摘要: This invention relates to a process for making a coupled, low vinyl 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 alkyltrialkoxysilane coupling agent having the formula R—Si—(OR′)3, where R is selected from branched alkyl radicals having from 3 to 12 carbon atoms, and R′ is a methyl group, and where the molar ratio of Si to Li is between 0.3 and 1.0, thereby forming a coupled block copolymer composition; andb) recovering the resulting coupled, low vinyl block copolymer composition.The invention also relates to the resulting coupled, low vinyl block copolymer compositions that are free from bromine-containing contaminants.
