BIOLOGICALLY DESTRUCTIBLE THERMOPLASTIC COMPOSITION Russian patent published in 2001 - IPC

Abstract RU 2174132 C1

FIELD: plastic materials based on natural polymers used for manufacturing thermally molded products of various configurations. SUBSTANCE: described is biologically destructible thermoplastic composition comprising, wt parts: cellulose diacetate containing acetate groups, 56.4-30; triacetin plasticizer, 30; biologically destructible starch filler, 10-50; and hydrolysis lignin filler, 10-20. Method makes it possible to prepare thermally molded composition based on highly filled cellulose diacetate. Products made from said composition are biologically destructible when exposed to natural effects (microflora of soil and water). EFFECT: improved properties of the biologically destructible composition. 2 cl, 2 tbl
