Abstract

The invention relates to the creation of polymer compositions based on PVC and ternary copolymers of acrylonitrile, butadiene and styrene (ABS plastics) and can be used for lining elements of combine harvesters operating under abrasive wear conditions. The invention makes it possible to increase abrasion resistance by 4 times due to the fact that the composition contains ethoxylated phenol of the formula C ₆ H ₅ O- (CH ₂ CH ₂ O) ₁₅ H 2.0 - 5.0 wt.h. as modifier. per 100 wt.h. blends of PVC and ABS plastic, taken in a 4: 1 ratio. The composition also contains, in parts by weight: dibutyl phthalate, 20.0 - 26.0

a mixture of salts of synthetic fatty acids cadmium and bari 1,2 - 1,8. 1 tab.
