FIELD: chemistry. ^ SUBSTANCE: invention relates to polymer compositions suitable for making moulded articles, particularly a polyethylene terephthalate composition for making plastic cards. The invention describes a composition containing the following in wt %: polyethylene terephthalate or polyethylene terephthalate based copolymer - up to 100, polyacrylonitrile butadienestyrene 1-30, synthetic amide or ester wax 0.1-3.0, polyolefin 0.5-12, thermal and thermo-oxidative decomposition stabiliser 0.1-1.0 and colouring additive 0.02-7.0. The polyolefin used is polyethylene, polypropylene, copolymer of ethylene with propylene or octane, and(or) polyolefin which contains carboxyl or epoxy functional groups. ^ EFFECT: composition improves mouldability of polymer articles and impact viscosity increases 1,8-5,5 times. ^ 1 cl, 1 tbl, 18 ex |
