Abstract :

The properties of mixtures and vulcanizates of polyvinyl chloride (PVC) and ethylene-propylene elastomers (SKEPT-40) with functional group polymers have been studied and it appears that the effectiveness of the application of functional group polymers (FQP) is characterized by the improvement of the complex properties of vulcanizates. As shown, among the FQP, the industrial scale production of PVC and the low cost of its use in the purchase of rubber mixtures based on SKEPT have been developed. In this regard, new composition mixtures were obtained by replacing the main polymers in rubber mixtures with 5÷30 mass parts of PVC based on SKEPT. The physical and mechanical properties of their technological and vulcanizates were studied. Experiments show that the sol-fraction and durability of vulcanizate in gasoline, gasoline-benzene (3:1) mixture, and metaxylol decrease with the increase of PVC content.

The reduction of the sol-fraction of the vulcanizate can be explained by the low swelling of PVC in the above-mentioned solvents. Therefore, the vulcanizate based on the SKEPT PVC mixture has a higher resistance to oil and gasoline than the vulcanizate based on unmodified SKEPT. It is learned that 10 mass. h to SKEPT. When PVC is included, the degree of swelling of the vulcanizate is reduced by 20% in gasoline, in the mixture of gasoline-benzene (3:1), M-xylene, and “, Avtol” oil, compared to the vulcanizate based on SKEPT. 30 c.h. and when included, the degree of swelling of the vulcanizate decreases by 2.7 times in gasoline, 2.3 times in gasoline-benzene (3:1) mixture, and 3.2 times in “Avtol-10” oil.
