| titleOfInvention | Method for production of stable copolymers of trioxane |
| abstract | FIELD: organic technology. SUBSTANCE: copolymerization of epichlorohydrin with 1,3,5-trioxane, their quantities being 10-25 and 90-75 respectively. Said copolymerization is carried out in solution of carbon tetrachloride, cation catalyst being used. Then thus prepared dispersion of half-finished product is separated of solvent and is affected by heat treatment. Said heat treatment takes place at 125-140 C in 2.5 solution of sodium hydroxide in mixture of N,N-dimethylformamide with water. EFFECT: improves efficiency of the method. 4 tbl |
