Structure of the interfacial layer and properties of crosslinked heterophase blends based on butadiene-nitrile and ethylene-propylene-diene elastomers

The density of the interfacial layer and the number of formed crosslinks have been estimated by means of swelling in selective solvents for heterophase blends of butadiene and ethylene-propylene elastomers. Ethylene-propylene-diene elastomers are characterized by an increased content of ethylene uni...

Summary:The density of the interfacial layer and the number of formed crosslinks have been estimated by means of swelling in selective solvents for heterophase blends of butadiene and ethylene-propylene elastomers. Ethylene-propylene-diene elastomers are characterized by an increased content of ethylene units and diene groups, a higher degree of isotacticity of propylene chain fragments, and a higher Mooney viscosity at low stereoregularity of the propylene units. The effects of the above parameters on the interfacial interaction and the kinetics of ozone degradation of the diene matrix have been studied.[PUBLICATION ABSTRACT]
