摘要:
This invention relates to reinforced thermoplastic moulding compositions prepared from biodegradable polymers, for example aliphatic or polyester amides, aliphatic polyester urethanes, and to the use thereof for the production of mouldings and to the mouldings, wherein the reinforcing materials are selected from wood flour, fibres of natural origin, minerals of natural origin, cellulose and cellulose derivatives.
摘要:
This invention relates to the production and use of coating powders based on saponified ethylene/vinyl acetate copolymers (EVA copolymers) modified with polyalkyl (meth) acrylates. Coatings and films produced from these coating powders are distinguished by the flexibility and elasticity thereof, especially at low temperatures.
摘要:
A thermoplastic moulding composition with improved flow properties being workable without difficulty by extrusion, injection moulding or blow moulding and resulting in colorless, transparent products with a smooth, glossy surface, comprising a mixture of(A)90 to 99.9% by weight of a polymer with a K-value of from 50 to 80, as measured at a temperature of 25.degree. C. in dimethyl formamide on a 0.5% by weight solution, which contains at least 50% by weight of acrylonitrile or methacrylonitrile or a mixture thereof in polymerized or grafted form, and(B)0.1 to 10% by weight of a statistical copolymer of copolymerized units of65 to 85% by weight of at least one acrylic acid alkyl ester with 1 to 8 carbon atoms in the alcohol component, and15 to 35% by weight of styrene,The copolymer B having an intrinsic viscosity [.eta.] of from 2.9 to 13.0 dl/g, as measured at 25.degree. C. in tetrahydrofuran.
