FIELD: polymers. SUBSTANCE: polymeric composition has, mas. p.: polyvinyl chloride 100; stabilizing agent containing, wt.-%: arylsulfamidocaproic acid 28-55; lead oxide 20-47, and calcium stearate - the rest 2.5-6.0; filler 1-10, and lubricant 0.2-1.5. Polymeric composition has additionally 3-20 mas. p. copolymer of methylmethacrylate or chlorinated polyethylene. Properties: fracture strength is 460-4580 bending cycles by 180 degrees up to sample rupture, degree of initial color retention is 0.84-0.95, thermal stability (t = 190 C) is 40-70 min. EFFECT: improved properties and quality. |
