Acrylic Derivatives of Glycidyl Ethers as Coagents for Peroxide Vulcanization of Hydrogenated Nitrile Butadiene Rubber

Abstract

The work is devoted to the assessment of the efficiency of using new reactive oligomers obtained by the interaction of domestic glycidyl ethers (oligopropylene glycol, homooligomer of epichlorohydrin, neopentyl glycol) and phenylglycidyl ether with acrylic acid, as co-agents of peroxide vulcanization of hydrogenated butadiene nitrile rubbers. It was found that the use of synthesized epoxy acrylates provides a comparable effect in terms of the rate and degree of peroxide vulcanization compared to rubbers containing imported products SR-213 and TMPTA-70. This circumstance and the achieved level of physical and mechanical properties allow us to propose the use of synthesized epoxy acrylates as co-agents of peroxide vulcanization, in particular, hydrogenated butadiene nitrile rubber, instead of imported ingredients of such a functional purpose.
