Compatibilization of polypropylene and butadiene–acrylonitrile rubber using an organic peroxide and an oligoether acrylate

The relationships and causes of changes in the deformation and strength properties of a blend of polypropylene with butadiene–acrylonitrile rubber with variation of the content of an organic peroxide, 2,5-dimethyl- 2,5-di(tert-butylperoxy)hexane, and an oligoether acrylate, triethylene glycol dimethacrylate, were studied. The observed changes in the deformation and strength properties of the blend were accounted for on the basis of the experimental data on the density of the vulcanization network of the butadiene–acrylonitrile rubber, on the morphological structure of the blend, on the adhesion between the polymers, and on the degree of crystallinity and molecular mass of polypropylene.
