FIELD: polymer products production.

SUBSTANCE: invention relates to a technology for producing polymer products using an additive principle and can be used to form products with reduced flammability using 3-D printing. The effect is achieved by using a photopolymerizable composition comprising a urethane polymer - oligourethane methacrylate of the MTM brand, a polymerizable compound FOM-2 dimethacrylate - a product of the interaction of methylphosphonic acid dichloride with glycidyl methacrylate, molecular weight 417.2 g/mol, photoinitiator - phenyl-bis (2.4, 6-trimethylbenzoyl)phosphine oxide and 1-(2,4-dimethylphenylazo)-2-naphthol, in the following ratio of components, parts by weight: oligourethane methacrylate MTM 25-75, dimethacrylate FOM-2 25-75, phenyl-bis(2, 4,6-trimethylbenzoyl)phosphine oxide 1, 1-(2,4-dimethylphenylazo)-2-naphthol (Sudan II) 0.1.

EFFECT: oligourethane methacrylate of the MTM brand, a polymerizable compound FOM-2 dimethacrylate creation.
