THERMOPLASTIC COMPOSITION Russian patent published in 2002 - IPC

FIELD: polymers. SUBSTANCE: invention relates to thermoplastic compositions based on mixtures of polymers and styrene copolymers. Method involves preparing the thermoplastic composition based on the mixture of polystyrene of the general purpose, 57.14-64.5 wt.-%; impact-resistant polystyrene, 25.8-40.0 wt. -% and linear block- copolymer of styrene and butadiene with content of blocks (25: 80)-(20: 75) taken from 2.86 to 9.70 wt.-%. Thermoplastic composition provides high isotropy of physical-chemical properties by contour of cast and thermoformed articles. EFFECT: improved properties of composition. 5 tbl
