Polymers Functionalized by Wood Resin and Oil-Gasoline-Resistant Rubber Based on Them

Abstract

Butadiene-nitrile (NBR-40) rubber and a functionalized polymer composition based on the biopolymer, which was formed in fruit trees and is called tree gum, was obtained, and the production of oil-gasoline resistant rubbers of this composition was investigated. For this purpose: the optimal recipe based on NBR-40 and tree gum rubber mixture was prepared based on optimal recipes and the mixture was vulcanized. In the composition prepared on the basis of NBR-40, wood cypress was used. As a result of IKS analysis of wood gum, which is a biopolymer, it was determined that it contains functional groups (COOH, OH, etc.)

Based on NBR-40+polyvinyl chloride (PVC) and biopolymer, the optimal recipe of the composition and the optimal vulcanization mode were studied and the optimal vulcanization mode was found.

Oil-gasoline resistance of rubber mixture and vulcanizate was studied;
