PHYSICOCHEMICAL PROPERTIES OF RUBBER COMPOSITIONS VULCANIZED BY POLYMERIC SULFUR

摘要

We study the physicochemical properties of rubbers vulcanized by polymeric and rhombic sulfur and determine the structural parameters of their cross-linking networks. It is shown that vulcanizates based on polymeric sulfur obtained as a result of plasma-chemical decomposition of hydrogen sulfide surpass rubbers vulcanized by rhombic sulfur by the main physicomechanical characteristics. It is shown that the migration of sulfur onto the surfaces of rubbers vulcanized by polymeric sulfur does not occur.
