POLYMERIC COMPOSITION Russian patent published in 1995 - IPC

Abstract RU 2048496 C1

FIELD: polymeric materials. SUBSTANCE: polymeric composition has, mas. p. polyvinyl chloride with isotactic triad number 22.0-22.8% and Fickentcher constant 60-73 100; dioctylphthalate as plasticizer 10-90, and thermostabilizing agent 3.4-7. After irradiation with dose 25 kGr the change value of integral optical film density is 0.3-0.4 immediately after gamma-irradiation and 0.58-0.65 after 1 year storage of irradiated samples. Extrusion material has 50-58 helics per 1 linear tube meter, index of creep limit smelt of casting composition is 140-152 g/10 min. Polymeric composition is used hematology. EFFECT: enhanced quality of composition. 1 tbl
