    摘要： Fiber-reinforced materials are produced by a process in which a heat-stable thermoplastic aromatic polyether A which contains reactive groups, preferably nitrile groups and/or sulfur bridges and/or arylthio or alkylthio groups, if necessary together with a heat-stable thermoplastic polymer B which does not contain any reactive groups, is applied onto reinforcing fibers, the resulting semi-finished product is molded and, in the molding obtained, the plastic matrix is crosslinked so that the glass transition temperature increases and it becomes virtually insoluble.

    摘要： Photopolymerizable compositions based on an elastomeric styrene-diene block polymer, one or more photopolymerizable olefinically unsaturated monomers and one or more photopolymerization initiators exhibit improved properties if they contain, as an essential constituent, an elastomeric block copolymer of the general structure A-B-C, where A is a thermoplastic, non-elastomeric polymer block based on styrene compounds and having a second order transition point above +25.degree. C., B is an elastomeric polymer block based on butadiene and/or isoprene and having a second order transition point below -20.degree. C. and C is a polymer block, different from B, having a second order transition point of from -30.degree. C. to +15.degree. C., C being either a homopolymer or copolymer block based on butadiene or isoprene or a random copolymer block based on conjugated dienes and styrene compounds. The photopolymerizable compositions may be used, inter alia, for the production of photo-curable adhesives, resilient and flexible sheet material and, in particular, flexographic relief printing plates.
