Multilayer thermoplastic composites comprising (a) a layer comprising a polyamide molding composition, (b) a layer comprising a polyester molding composition, and (c) an adhesion promoter intermediate layer (a) and layer (c) find use as structural components in the electrical engineering, machine production and automotive industries, and for foodstuff packaging films or multilayer pipes.

Multilayer thermoplastic composites

A process for bonding a polyamide containing thermoplastic material and a rubber, comprising covulcanizing, in the presence of a vulcanization system, a thermoplastic component which contains at least 30% by wt. of an aliphatic polyamide and a rubber composition which, based on 100 parts by weight of a carboxyl group-containing rubber, contains 100-300 parts by wt. of fillers, and 1-10 parts by wt. of peroxidic vulcanizing agents.

Process for chemically bonding molding compositions based on aliphatic

The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degradation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.

Polyesters are modified by adding an aqueous latex having a solids content of &lt;50% by weight. The synthetic resin contained in the latex has a glass transition temperature of .ltoreq.0.degree. C. and contains 0.1-20 mol-% of functional groups.

Molding compositions based on linear, high-molecular weight polyesters

A thermoplastic resin composition, which comprises (a) from 5 to 85 parts by weight of a melted or remelted preliminary molding compound consisting of from 60 to 98 parts by weight of polyphenylene ethers, 40 to 2 parts by weight of polyoctylenes, from 0.1 to 5 parts by weight of maleic anhydride and from 0.1 to 5 parts by weight of a further acid derivative which has a melting point below 100.degree. C. and which is selected from the group consisting of an unsaturated mono- or dicarboxylic acid having up to 14 carbon atoms, an anhydride thereof, which excludes maleic anhydride, and an ester of mono- or dicarboxylic acid with an alcohol of up to 6 carbon atoms; and (b) from 95 to 15 parts by weight of an aliphatic homopolyamide or a copolyamide containing a preponderant amount of aliphatic monomer units.

Impact-resistant thermoplastic molding compounds based on polyphenylene

The invention relates to a process for the production of molding compositions from a thermoplastic polycondensation resin susceptible to degredation at high temperature in the presence of H.sub.2 O, to which is admixed a second synthetic resin, present as an aqueous latex, at temperatures in the range of 150.degree.-300.degree. C. and under a pressure in the range of 1-100 bar under the effect of high shear forces, for a time sufficient to provide the desired molding composition without substantially degrading the polycondensation resin.
