FIELD: chemistry. ^ SUBSTANCE: invention relates to a photopolymerising composition. The composition contains polysulfone based on 2,2-bis(4-oxyphenyl)propane and 4,4'-dichlorodiphenylsulfone with molecular weight of 40000-56000, a solvent, a polymerisable compound and a photoinitiator. The solvent contained in the composition is styrene, the polymerisable compound is a product of reacting diacyl chloride of methyl-phosphonic acid with glycidyl methacrylate with molecular weight of 417.2 g/mol, with 17.03% and 7.43% content of chlorine and phosphorus respectively, and the photoinitiator is 2,4,6-trimethylbenzoyl diphenylphosphine oxide. The components are in the following ratio (pts. wt): polysufone based on 2,2-bis(4-oxyphenyl)propane and 4,4'-dichlorodiphenylsulfone with molecular weight of 40000-56000 35-45, styrene 65-55, product of reacting diacyl chloride of methyl-phosphonic acid with glycidyl methacrylate with molecular weight of 417.2 g/mol, with 17.03% and 7.43% content of chlorine and phosphorus respectively 20-30, 2,4,6-trimethylbenzoyl diphenylphosphine oxide 3-5. ^ EFFECT: invention enables to obtain low flammability materials, enables formation of a coating with thickness of 0,4-0,6 mm in a single process step with minimal percentage of volatile components. ^ 6 ex, 2 tbl |
