PRODUCTS MADE OF POLYISOPRENE CATALYZED BY ZIEGLER-NATT Russian patent published in 2022 - IPC C08F36/08 C08J3/12 A61F6/04 C08L19/00 C08L9/00 

Abstract RU 2778125 C2

FIELD: chemistry.

SUBSTANCE: invention relates to polymer products of synthetic polyisoprene resins. A polymer product is proposed, different in that it contains an elastomeric layer containing cured particles of synthetic polyisoprene, which contain polyisoprene material catalyzed by Ziegler-Natt and sulfur cross-links, where particles of synthetic polyisoprene are preliminary vulcanized, and the elastomeric layer contains a post-vulcanized structure having a molecular weight between cross-links (Mc) of less than 11,000 g/mol. A method for the production of the specified polymer product and a condom are also proposed.

EFFECT: proposed polymer products are thin, durable, and non-allergic.
