THERMOPLASTISCHE RECYCLING-FORMMASSE

摘要

Thermoplastic moulding compositions containing A) from 35 to 65 % by weight of propylene polymers comprising A1) from 0 to 80 % by weight, based on A), of non-regranulated propylene polymers, and A2) from 20 to 100 % by weight, based on A), of regranulated propylene polymers obtained by comminution of mouldings, B) from 10 to 40 % by weight of thermoplastic regranules obtained by comminuting mouldings and containing one or more thermoplastics from the group consisting of polycarbonates, acrylonitrile-butadiene-styrene (ABS) polymers, acrylonitrile-styrene-acrylate (ASA) polymers, polyesters and polyamides (nylons), C) from 10 to 40 % by weight of particulate fillers or fibrous fillers having a fibre length in the range from 50 to 500 mu m, and in addition D) up to 5 % by weight, based on components A to C, of at least one reactive alpha ,ss-unsaturated compound which, in addition to a double bond, contains one or more carbonyl, carboxyl, carboxylate, acid anhydride, acid amide, acid imide, carboxylic ester, amino, hydroxyl, epoxy, oxazoline, urethane, urea, lactam or halobenzyl group, and E) up to 0.5 % by weight, based on components A to C, of a free-radical former. a
