    Abstract: Thermoplastic moulding compsn. based on polyphenylene ether is produced by mixing: (A) 3-96.99 (wt.)%, w.r.t. A + B + C, of a modified polyphenylene ether (I), prepd. from (a1) 70-99.95%, w.r.t. A, of a mixt. of min. 30% polyphenylene ether and max. 70% vinyl-aromatic polymer, (a2) 0.05-10%, w.r.t. A, of (a21) a monomer with a polymerisable double bond, contg. amide gps., (a22) a monomer with a polymerisable double bond, contg. lactam gps., and/or (a23) an alpha,beta-unsatd. dicarbonyl cpd. and (a3) 0-20%, w.r.t. A, of another comonomer, which can react with al under the reaction conditions, (B) 3-87%, w.r.t. A + B + C, of a thermoplastic copolymer, produced in the melt from (b1) 80-99.95%, w.r.t. B, of a basic polymer contg. acrylic and phenyl gps. and (b2) 0.05-20%, w.r.t. B, of an alpha,beta-unsatd. dicarbonyl cpd.; and (C) 0.01-10%, w.r.t. A + B + C, of a cpd. with at least 2 OH, SH, epoxy and/or amino substits.

    Abstract: The compsns. (I) comprise, on wt. (A)-(E), (A) 3-97wt.% resin contg., on wt. (A), (a1) 60-85wt.% at least one 8-9C vinylaromatic monomer and (a2) 40-15wt.% acrylonitrile units; opt. (B) up to 40wt.% elastomer of glass temp. below 0 deg.C as graft copolymer from (a1) and (a2); (C) 97-3wt.% poly(phenylene ether); (D) 0.5-40wt.% at least one P-contg. flame retardant cpd.; and (E) 0.3-95wt.% at least one copolymer comprising terpolymeric main chain with side chains attached through condensn. Wt.-average mol. wt. (by G.P.C.) of main chain of component (E) is 10 power 4 to 10 power 7, and that of side chains is 200-22000. The main chain contains, polymerised, (e1) 60-91wt.% at least one 8-9C vinylaromatic monomer, (e2) 40-9wt.% acrylonitrile, and (e3) 0.3-10wt.% at least one ester of (meth)acrylic acid with an ester-forming alcohol. Each side chain has at least one, opt. unsubstd., poly(phenylene ether) residue (PPE) which links, via the gp.X (residue of an at least bifunctional couplinq agent), the polymer -XPPE of the side gps. to the monomer(s) capable of ether formation (i.e., side chains -XPPE are linked to O atoms directly attached to main chain).
