SUPHUR-FREE, ZINC-FREE CURE SYSTEM FOR HALOBUTYL AND HALOGEN CONTAINING POLYMERS Russian patent published in 2018 - IPC C08J3/24 C08C19/32 C08F210/12 C08F8/40 C08K5/50 

Abstract RU 2656042 C2

FIELD: chemistry.

SUBSTANCE: invention relates to a cured sulphur free compound and a zinc oxide (ZnO) free compound, as well as to a process for its preparation. Compound includes: (a) a polymer selected from a group consisting of halobutyl polymers and halogen-containing polymers, and (b) a multifunctional phosphine crosslinking agent selected from a group consisting of 1,3-bis(diphenylphosphino)propane, 1,4-bis(diphenylphosphino)butane and 1,5-bis(diphenylphosphino)pentane.

EFFECT: technical result consists in obtaining a compound that provides a significant reduction in residual deformation under compression.
