    IPC: C08F283/08

    Abstract: A process for the preparation of modified polyphenylene ether resins by grafting fumaric acid, preferably at from 270 DEG to 350 DEG C., onto polyphenylene ethers which are mixed with vinylaromatic polymers, and modified polyphenylene ether resins consisting of from 4.95 to 95 parts by weight of polyphenylene ether, from 95 to 4.95 parts by weight of vinylaromatic polymer and from 0.05 to 10 parts by weight of grafted fumaric acid.

    Abstract: Thermoplastic molding materials contain, as essential components, (A) 5-95% by weight of a polyamide; (B) 5-95% by weight of a modified polyphenylene ether, prepared from (b1) 4.95-99.9% by weight of a polyphenylene ether, (b2) 0-90% by weight of a vinylaromatic polymer, (b3) 0.05-10% by weight of one or more compounds from the group consisting of (b31) an alpha , beta -unsaturated dicarbonyl compound, (b32) a monomer containing amide groups and a polymerizable double bond and (b33) a monomer containing lactam groups and a polymerizable double bond, (b4) 0-80% by weight of further graft-active monomers and (b5) 0.01-0.09% by weight of a free radical initiator, (C) 0-90% by weight of an unmodified polyphenylene ether, (D) 0-45% by weight of a vinylaromatic polymer and (E) 0-40% by weight of a rubber impact modifier.

    Abstract: Graft polymers of (A) a polyphenylene ether as a base polymer and (B) a half ester of an unsaturated dicarboxylic acid of the general formula I as a graft monomer, where R1 is C1-C25-alkyl, C2-C25-alkylene or aryl, R2 and R3 are each H, Br, Cl or one of the radicals R1, and Q is H or an alkali metal, an alkaline earth metal or an ammonium cation, with or without (C) further olefinically unsaturated monomers, and their preparation.
