Abstract:
The present invention relates to a method for producing molded parts from fiber-reinforced composite materials and to binders for preforming textile structures in the production of structural materials according to the RIM or RTM method.
Abstract:
The present invention relates to a method for producing a block copolymer containing polyaryl ether blocks and polyalkylene oxide blocks, comprising the reaction of an HO-terminated polyaryl ether with a monomeric alkylene oxide. The present invention also relates to a block copolymer that can be obtained from said method. The invention further relates to a triblock polymer having polyalkylene oxide/polyaryl ether/polyalkylene oxide blocks.
Abstract:
The present invention relates to polyarylene ether block copolymers according to the general formula A-K-X-K-A, where -X- is a polyarylene ether segment with number-average molar mass of at least 5000 g/mol, and A- is a segment of the general structure R2NH-(R1-NH-CO-Ar-CO-NH)n-R1-NH-, in which R1 is a linear or branched alkylene group having from 2 to 12 carbon atoms and Ar is an arylene group having from 6 to 18 carbon atoms, and R2 is selected from aryloyl, alkyloyl, and H, and in which the number average of n is from 1 to 3, and there is a coupling group K of the structure -CO-Ar3-CO- linking each A to X, in which Ar13 is an aromatic group having from 6 to 18 carbon atoms. The present invention also relates to a process for the production of the polyarylene ether block copolymers of the invention, to polymer compositions comprising the polyarylene ether block copolymers of the invention, and also to the use thereof for the production of moldings, of films, of fibers, or of foams.
Abstract:
The invention relates to thermoplastic molding compounds containing the following components: (A1) at least one polyarylene thermite consisting of no more than 0.5 phenolic end groups per polymer chain on average, (A2) optionally at least one polyarylene thermite consisting of at least 1.5 phenolic end groups per polymer chain on average, (B) at least one polyarylene sulfide, (C) at least one hyperbranched polymer selected from hyperbranched polycarbonates and hyberbranched polyesters, (D) optionally at least one functionalized polyarylene ether comprising carboxyl groups, (E) optionally at least one fibrous or particulate filler, and (F) optionally further additives and/or auxiliary processing agents. The invention further relates to a method for producing the thermoplastic molding compounds according to the invention, to the use thereof for producing molded parts, fibers, foams, or films, and to the molded parts, fibers, foams, and films that can be obtained in this manner.
