REACTION EXTRUSION OF DYNAMIC ELASTOPLASTS ON THE BASIS OF POLYOLEFINES AND BUTADIEN-NITRIL RUBBER

The influence of the concentration of butadiene-nitrile rubber and vulcanizing agents (dicumyl peroxide and sulphur) on the technological process of extrusion of elastoplasts on the basis of a mixture of low-density polyethylene and polypropylene is considered. It was found that with a minimum concentration of dicumyl peroxide (0.5 mass %) or sulphur (1–5 mass %), it is possible to obtain dynamically vulcanized elastoplasts with a unique combination of structure and properties
