METHOD OF POLYMERIC COMPOSITION PREPARING Russian patent published in 1995 - IPC

Abstract SU 1702676 A1

FIELD: polymer processing. SUBSTANCE: method involves additional addition of methylmethacrylate copolymer with 5 wt.-% methyl-, ethyl- or butylacrylate to the mixture of polyvinyl chloride with plasticizer, thermostabilizer and antioxidant at the stage of cooling at 20-40 C. Mixture is obtained by mixing with component at 60-80 C and heated up to 80-100 C. Polymeric composition is used for film making (thickness is 10-60 mcm) used for package, sheets etc. EFFECT: increased rupture strength, retained relative elongation. 1 tbl
