FIELD: polymer production. SUBSTANCE: stabilizer may be utilized when processing compositions of chlorine-containing polymers such as polyvinyl chloride, vinyl chloride copolymers, etc. into various articles (film materials, bottles, shaped objects, pipes, etc.). To improve total performance of materials resulted from processing of stabilized chlorine-containing polymers, stabilizer employed must include (in wt %): arylsulphonamidocapronic acid, 56-70; calcium oxide, 4.2-6.3; and zinc stearate, the balance; or arylsulphonamidocapronic acid, 28-55; lead oxide, 20-47; and calcium stearate, the balance. Stabilizer additionally contains 4- 8% maleic anhydride. Materials produced using this stabilizer, after aging, retain their initial color at the level of 0.82-0.96, have heat resistance 45-95 min, yellowness coefficient 13-24%, transparency coefficient 80-92%, extrusion output 130-170 g/min (for materials produced using 1st stabilizer version) and break strength 480-960 bending cycles (for materials produced using 2nd stabilizer version). EFFECT: improved performance of material. |
