FIELD: polymers production. SUBSTANCE: oligocarbonate-dimethacrylate-based composition for manufacturing photopolymer products by anaerobic stereolithography technique contains triethylene glycol dimethacrylate, organocopper compound with general formula 1: <EMI ID=0.589 HE=36 WI=54 TI=CHI> (1), where n= 2 and R is -(CH<SB>2</SB>-CH<SB>2</SB>-O)<SB>3</SB>-, unsaturated monomer - butyl methacrylate, and photoinitiator - 2,2-dimethoxy-2-phenylacetophenone. EFFECT: accelerated hardening of composition and reduced its volume shrinkage upon hardening. 2 dwg, 1 tbl, 3 ex
