METHOD OF PRODUCING THERMO- AND HEAT-RESISTANT POLYMERS BASED ON TRIS-[(1-HALOMETHYL-2-ALLYLOXY)ETHOXY]PHOSPHINES Russian patent published in 2019 - IPC C07F9/141 C08G79/04

Abstract RU 2700698 C1

FIELD: technological processes.

SUBSTANCE: present invention relates to polymerisation processes, in particular to the development of reactive photopolymerisable compositions which can be used for accelerated formation of thermo- and heat-resistant coatings with low flammability. Method of producing thermo- and heat-resistant polymers based on tris-[(1-halomethyl-2-allyloxy)ethoxy]phosphines involves radical polymerisation of tris-[(1-halomethyl-2-allyloxy)ethoxy]phosphine in the presence of a photoinitiator of polymerisation – bisphenyl(2,4,6-trimethylbenzoyl)phosphine oxide, taken in amount of 0.5 wt% of monomer. Polymerisation is carried out in the presence of ultraviolet radiation.

EFFECT: simple method of obtaining thermo- and heat-resistant polymers based on tris-[(1-halomethyl-2-allyloxy)ethoxy]phosphines, high thermal stability of polymers, as well as wider field of use thereof.
