METHOD OF PRODUCING THERMO- AND HEAT-RESISTANT POLYMERS BASED ON BIS-(1-HALOMETHYL-2-ALLYLOXYETHOXY)-(1-HALOMETHYL-2-PHENOXYETHOXY)PHOSPHINES Russian patent published in 2020 - IPC C08F2/48 C08F2/50 C07F9/53 C08G79/04 

Abstract RU 2712062 C1

FIELD: technological processes.

SUBSTANCE: invention relates to polymerization processes, particularly to the development of reactive photopolymerizable compositions. Thermo- and heat-resistant polymer based on bis-(1-halomethyl-2-allyloxy-ethoxy)-(1-halomethyl-2-phenoxyethoxy) phosphines is obtained by radical polymerization of bis-(1-halomethyl-2-allyloxy-ethoxy)-(1-halomethyl-2-phenoxy-ethoxy] phosphine in presence of 0.5 wt% photoinitiator. Polymerization initiator used is a photoinitiator of bisphenyl(2,4,6-trimethylbenzoyl)phosphine oxide. 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-allyloxy-ethoxy)-(1-halomethyl-2-phenoxyethoxy) phosphines, high thermal stability of polymers, as well as wider field of use thereof.
