| titleOfInvention | Method for preparing phosphorus-chlorine-containing methacrylates |
| abstract | FIELD: chemistry of organophosphorus compounds. n SUBSTANCE: invention relates to the improved method for synthesis phosphorus-chlorine-containing methacrylates that can be used in synthesis of polymeric, among them, uncolored, optically transparent and composition materials with reduced inflammability. Invention describes a method for synthesis of phosphorus-chlorine-containing methacrylates of the general formula: n wherein R means lower alkyl, chloroalkyl, alkoxyl, phenoxyl or group of the formula: n R 1 means lower alkoxyl, phenoxyl or group of the formula: n Method involves interaction of phosphoric pentavalent acid chloroanhydrides with methacrylic acid glycidyl ester at heating in the presence of hexamethylenephosphorotriamide or dimethylformamide as a catalyst wherein catalyst is taken in the amount 0.3-0.6% of reagents mass, and process is carried out at rise of temperature from 40°C to 80°C in the presence of compound chosen from the group: alkyl- or alkoxy-substituted phenols taken in the amount 0.03-0.3% of reagents mass. Method provides decreasing water absorption of (co)polymerization products of synthesized phosphorus-chlorine-containing methacrylates and reducing retention time of surface stickiness of fiber glass synthesized on their basis and at retention the level of other properties, among them transparence and colorless. n EFFECT: improved method of synthesis, improved and valuable properties of compounds. n 2 tbl, 10 ex |
