CURABLE POLYMER COMPOSITION AND METHOD OF MAKING A HARDENED PRODUCT THEREFROM Russian patent published in 2019 - IPC G03F7/31 G03F7/32 G03F7/04 C08L61/10 

FIELD: technological processes.

SUBSTANCE: invention relates to curable polymer compositions which contain photo-polymerizable components which are curable by ultraviolet radiation to form cured products. Disclosed is a curable polymer composition comprising a thermo-polymerizable component which is a phenol-formaldehyde resin, a modified propargyl halide (20.0–40.0 wt%), and a photopolymer composition which contains (wt%): triethylene glycol dimethacrylic ester (5–20), styrene (14–19), bisphenol A based vinyl ester resin or based on novolac phenol-formaldehyde resin (35.0–50.0) and photoinitiator (0.5–1.0). Also disclosed is a method of producing a solidified product from said curable polymer composition.

EFFECT: disclosed composition is stable during storage and enables the disclosed method to obtain articles with improved heat resistance.
