Abstract: An electric cable contains a cable insulation having high resistance to the formation or growth of water trees and having high aging resistance and good processibility and consisting of an ethylene polymer and from 0.5 to 40% by weight of an ethylene copolymer ionomer which contains, in addition to predominant amounts of ethylene, a C.sub.3 -C.sub.6 -alkenecarboxylic acid or a C.sub.4 -C.sub.6 -alkenedicarboxylic acid or -dicarboxylic anhydride as copolymerized units, some of the carboxyl groups or carboxylic anhydride groups having been converted into ammonium salts of tertiary amines.

Abstract: Thermoplastic molding materials which consist of polyesters and polycarbonates and have good low-temperature impact strength contain(A) from 5 to 94 parts by weight of one or more aliphatic polyesters of an aromatic dicarboxylic acid,(B) from 5 to 94 parts by weight of one or more aromatic polycarbonates,(C) from 1 to 40 parts by weight of one or more olefin polymers which contain epoxide groups,the amounts of components A, B and C summing to 100 parts by weight, and, if required,(D) additives in effective amounts.

Abstract: Thermoplastic polyester molding materials having low-temperature impact strength essentially consist of(A) from 20 to 79 parts by weight of one or more aliphatic polyesters of an aromatic dicarboxylic acid having a relative viscosity of from 1.2 to 1.8,(B) from 20 to 79 parts by weight of one or more aromatic polycarbonates having a relative viscosity of from 1.2 to 1.5,(C) from 1 to 40 parts by weight of an elastomer blend consisting of1. from 5 to 95% by weight of an ethylene copolymer composed of(a) from 40 to 99% by weight of ethylene and(b) from 1 to 60% by weight of one or more comonomers containing carboxyl groups and/or derivatives of carboxyl groups, and2. from 5 to 95% by weight of an elastomeric graft polymer which is prepared by emulsion polymerization and composed of(a) from 70 to 95% by weight of a substantially crosslinked grafting base having a glass transition temperature T.sub.g below -20.degree. C.

Abstract: Thermoplastic molding materials based on(A) polycarbonates and(B) polyesters containing from 1 to 30% by weight, based on (A)+(B)+(C),(C) of a graft copolymer based on(C.sub.1) from 60 to 99% by weight of an elastomeric component based on acrylic acid esters, methacrylic acid esters and/or conjugated dienes as well as, if desired, further comonomers, as graft base and(C.sub.2) from 1 to 40% by weight of an expoxy-containing monomer as applied graft.
