摘要:
Thermoplastic polyester molding materials essentially contain(A) from 20 to 89% by weight of one or more aliphatic polyesters of an aromatic dicarboxylic acid,(B) from 10 to 79% by weight of one or more aromatic polycarbonates and(C) from 1 to 40% by weight of an elastomer or of a mixture of elastomers consisting ofCA from 5 to 100% by weight of an elastomeric graft polymer composed ofCA1 not less than 50% by weight of a grafting base having a glass transition temperature T.sub.g of less than -20.degree. C.,CA2 from 5 to 20% by weight of a first graft shell consisting of a mixture of a C.sub.1 -C.sub.8 -alkyl ester of acrylic acid and a vinylaromatic in a weight ratio of from 5:95 to 70:30 andCA3 from 10 to 30% by weight of a second graft shell consisting of one or more polymers having a glass transition temperature T.sub.g above 20.degree. C. andCB from 0 to 95% by weight of an ethylene copolymer composed of CB1 from 40 to 99% by weight of ethylene and CB2 from 1 to 60% by weight of one or more comonomers containing carboxyl groups and/or carboxyl group derivatives,the sum of A to C, CA and CB, CA1 to CA3 and of CB1 and CB2 being 100% by weight in each case.
摘要:
Aqueous dispersions of copolymers having a glass transition temperature of not more than -45.degree. C. and a K value greater than 80 consist of not less than 80% by weight of acrylates of alkanols of 8 to 12 carbon atoms, from 1 to 4% by weight of .alpha.,.beta.- monoolefinically unsaturated carboxylic acids and/or their amide derivatives and from 0.1 to 3% by weight of .alpha.-methylstyrene, and are used for the production of self-adhesive structures having good tack at as low as -40.degree. C.
