- the sum of components (a)-(c) being 100% by weight, with or without
- (C) effective amounts of conventional additives.
- 2. A nylon molding material having high impact strength, as claimed in claim 1, wherein component (b) is n-butyl acrylate.
- 3. A nylon molding material which has high impact strength and contains
- (A) a thermoplastic nylon having a relative viscosity of from 2.5 to 5, and
- (B) from 5 to 65% by weight, based on (A), of a non-crosslinked copolymer which contains three or more components and is characterized by a melting range of from 40.degree. to 100.degree. C., a glass transition temperature of below -20.degree. C. and a shear modulus of less than 100 (Nmm.sup.-2) at -20.degree. C., less than 50 (Nmm.sup.-2) at 0.degree. C. and less than 20 (Nmm.sup.-2) at +20.degree. C.; said copolymer comprising:
- (a) from 55 to 75% by weight of ethylene,
- (b) from 20 to 40% by weight of one or more primary or secondary C.sub.2 -C.sub.8 -alkyl acrylates or methacrylates and
- (c) from 0.5 to 8% by weight of maleic anhydride,
- the sum of components (a)-(c) being 100% by weight, with or without
- (C) effective amounts of conventional additives.
- 4. A nylon molding material which has high impact strength and contains
- (A) a thermoplastic nylon having a relative viscosity of from 2.5 to 5, and
- (B) from 5 to 65% by weight, based on (A), of a non-crosslinked copolymer which contains three or more components and is characterized by a melting range of from 40.degree. to 100.degree. C., a glass transition temperature of below 20.degree. C. and a shear modulus of less than 100 (Nmm.sup.-2) at -20.degree. C., less than 50 (Nmm.sup.-2) at 0.degree. C. and less than 20 (Nmm.sup.-2) at +20 C.; said copolymer comprising:
