METHOD OF PRODUCING THERMO- AND HEAT-RESISTANT POLYMERS BASED ON BIS-(1-HALOMETHYL-2-METHACRYLOXYETHOXY)-(1-HALOMETHYL-2-PHENOXYETHOXY)PHOSPHINES Russian patent published in 2020 - IPC C07F9/141 C08G79/04

Abstract RU 2717549 C1

FIELD: chemistry.

SUBSTANCE: present invention relates to a method of producing thermo- and heat-resistant polymers based on bis-(1-halomethyl-2-methacryloxyethoxy)-(1-halomethyl-2-phenoxyethoxy)phosphines. Proposed method consists in radical polymerization of bis-(1-halomethyl-2-methacryloxyethoxy)-(1-halomethyl-2-phenoxyethoxy)phosphine in presence of polymerization initiator. Initiator of polymerization is a photoinitiator – bisphenyl(2,4,6-trimethylbenzoyl)phosphine oxide. Initiator is taken in amount of 0.5 wt% of monomer. Polymerization is carried out in the presence of ultraviolet radiation.

EFFECT: simple method of producing thermo- and heat-resistant polymers based on bis-(1-halomethyl-2-methacryloxyethoxy)-(1-halomethyl-2-phenoxyethoxy)phosphines, high thermal stability of polymers, as well as wider field of use thereof.
