A method of effecting chemical bonding between a thermoplastic polymer having the recurring unit: ##STR1## and a synthetic rubber, comprising, covulcanizing a polyphenylene ether containing, thermoplastic molding compound and said synthetic rubber by heating the mixture in the presence of a vulcanizing system, said polyphenylene ether containing, thermoplastic molding compound having the composition, a) 100 parts by weight of polymers of ortho-substituted phenols having the formula: ##STR2## where R.sub.1 and R.sub.2 independently represent a methyl group or hydrogen, and R.sub.3 and R.sub.4 represent an alkyl group with up to 6 carbon atoms, or R.sub.3 represents hydrogen and R.sub.4 represents a tertiary alkyl group with up to 6 carbon atoms, b) 0-20 parts by weight polyalkenylenes, and, c) 0-100 parts by weight styrene polymers; and said synthetic rubber containing double bonds, being combined with fillers and plasticizers and being a member selected from the group consisting of (1) SBR rubbers, (2) BR rubbers, (3) IR rubbers, (4) IIR rubbers, (5) mixtures of at least two rubbers (1)-(4), and (6) mixtures of any one or more rubbers (1)-(5) with up to 80 wt. % of the rubber mixture being substituted by CIIR rubbers, up to 95 wt. % of the rubber mixture being substituted by NR rubber, up to 60 wt. % of the rubber mixture being substituted by CR rubber or up to 25 wt. % of the rubber mixture being substituted by NBR rubber.

Method of preparing a chemical composition comprised of molding

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

Components made from at least two molded materials A and B which are firmly bonded together, and in which

Components made from continuous fiber reinforced polyamide molding

A process for bonding a thermoplastic PPE-containing polymer and a rubber by covulcanization, comprising the steps of:

Process for producing a chemical bond between molding materials based on

Composite parts of firmly bonded molding materials, comprising a thermoplastic material containing polyphenylene ether, a layer of SBR or SBS rubber or a mixture thereof surrounding the thermoplastic material, if necessary, an intermediate layer comprising a powdered SBR rubber which may contain a filler, and a rubber containing carbon-carbon double bonds covulcanized with the layer of SBR or SBS rubber. The invention also provides a method for producing the composite part comprising treating the thermoplastic material with a solution of a SBR or SBS rubber in an organic solvent or with an aqueous latex of the rubber, if necessary, completely or partially removing the organic solvent or water, if necessary, treating the dried mass with a powdered SBR rubber which may contain a filler, and covulcanizing with a rubber containing carbon-carbon double bonds.

Parts based on polyphenylene ethers and rubbers as well as methods for

The invention relates to component parts comprised of at least two alternating layers comprising a polyphenylene ether-containing (PPE-containing) molded piece and an elastomeric thermoplastic block copolymer of the type A-B-A, wherewith A represents a styrene block and B a soft phase block; and a method of manufacturing the same.

Component parts comprised of polyphenylene ethers and elastomeric

Structural components are produced which have at least 2 layers A and B. Layer A contains, as a matrix, a thermoplastic resin plastic containing a polyphenylene ether and fibrous reinforcing supports disposed therein. Layer B is a rubber which is obtained through the vulcanization of certain caoutchoucs containing double bonds.
