FIELD: chemistry.
SUBSTANCE: composition contains a mixture of: (i) aromatic polycarbonate; (ii) a graft copolymer which contains polyacrylonitrile; and (iii) a non-cross-linked polymer having weight-average molecular weight (Mw) less than or equal to 65000 Da. The graft-copolymer contains acrylostyrene-acrylonitrile polymer, acrylonitrile-ethylene-propylene-diene-styrene polymer, olefin-styrene-acrylonitrile polymer or acrylonitrile-butadiene-styrene polymer. The composition can additionally contain a modifying additive based on methacrylate-butadiene-styrene which increases impact strength. The composition can additionally contain reinforcing fibre. The non-cross-linked acrylic polymer increases the melt flow rate of the mixture and shortens the duration of the process cycle when preparing the mixture.
EFFECT: invention improves the technology of processing polymer mixtures based on aromatic polycarbonate.
