PHOSPHASE-CONTAINING OLIGOESTER ACRYLATE AND METHOD FOR ITS PRODUCTION Russian patent published in 2021 - IPC C08K5/5399 C08L85/02 C08G79/25 C07F9/6521 A61K6/884 

FIELD: chemistry.

SUBSTANCE: invention relates to oligoester acrylates. Proposed is a phosphazene-containing oligoester acrylate containing bisphenol glycidyl methacrylate or bisphenol glycidyl acrylate in an amount of 97 to 50 wt% and a polymerizable phosphazene compound in an amount of 3 to 50 wt% The polymerizable phosphazene compound has the general formula - (I), where Ar is a radical representing a fragment of a bisphenol A radical -OC₆H₄C(CH₃) ₂C₆H₄O- or another diphenol, and R is a methacrylic or acrylic radical. A method for producing said phosphazene-containing oligoester acrylate is also proposed.

EFFECT: proposed phosphazene-containing oligoester acrylate can be used as a component of polymer and composite materials with improved physicochemical properties, including in the composition of photocurable compositions, binders for reinforced plastics, polymer dental compositions, as well as materials obtained by additive technology.
