METHOD OF PREPARING OF SHOCK-RESISTANT COMPOSITION Russian patent published in 1995 - IPC

FIELD: shock-resistant composition materials. SUBSTANCE: granules of polyalkyleneterephthalate were mixed with polyacrylonitrilebutadienestyrene granules, extruded at 250-280 C, cooled and granulated. Mass ratio of polyalkyleneterephthalate and polyacrylonitrilebutadienestyrene is (1-4):(1-4). Prepared granules were mixed with polycarbonate granules, mixture is dried at 90-100 C for 14 h, extruded, cooled and granulated. Mass ratio of components in composition is, wt.-%: mixture of polyalkyleneterephthalate and polyacrylonitrilebutadienestyrene 5-40, and polycarbonate - the rest up to 100. EFFECT: improved method of composition preparing. 1 tbl
