摘要

FIELD: manufacture of cellulose triacetate-based film materials. SUBSTANCE: solution comprises, wt.%: cellulose triacetate 3.0-4.0; modifying polystyrene additive, 0.0017-0.0036; and methylene chloride, up to 100. Method uses film-forming solution which is simple in composition and ecologically safe. Solution contains small amount of cheaper modifying polymeric additive. EFFECT: greater strength of film materials and elasticity thereof. 8 ex, 1 tbl
