THERMOPLASTIC MOLDING COMPOSITION Russian patent published in 2003 - IPC

FIELD: polymers. SUBSTANCE: invention relates to preparing thermoplastic compositions used for molding based on waste of polyethylene terephthalate (PETP). Composition contains the following components, %: waste of PETP with specific viscosity 0.1-0.25, 53.8-77.52; impact-strength polystyrene, 15.2-37.4; polycarbonate, 0.78- 2.6; mixture of calcium and mineral oil I-50 in their mass ratio = (80-90)-(10-20), 6.2-6.5. Composition can contain also, %: waste of PETP, 46.3-50.0; polycarbonate, 33.4-34.3; acrylonitrilebutadienestyrene thermoplast, 13.9-14.7; mixture of calcium oxide and mineral oil I-50 in above given ratio, 2.7-4.7. Invention allows using in compositions components with enhanced content of moisture without alternation of physical-mechanical properties of composition and materials based on thereof. EFFECT: improved, enhanced and valuable properties of composition. 2 cl, 2 tbl, 7 ex
