Influence of the nature of the cyclic component in the composition of ternary ethylene-propylene rubber on the structural and dynamic state of blends with chlorosulphonated polyethylene

摘要

NMR relaxometry showed that, in spite of its small proportion in the composition of the macrochain, corresponding to the "small additive" range (≤5 parts), the cyclic component has a considerable effect on the structural and dynamic state of ternary copolymeric ethylene-propylene rubber in a blend with chlorosulphonated polyethylene owing to the topochemical processes occurring during mixing of the polymers. The results obtained also indicate the most probable or stable centres of intermolecular interactions of a non-chemical nature that determine the short-range conformational order in the given blends.
