Flame-retardant material containing phosphorous

摘要

Phosphorus containing flame retardant obtained by (i) reacting a phosphorus compound, which is 9,10-dihydro-9-oxa-10-phospha-phenanthren-10-oxide with an unsaturated dicarboxylic acid to obtain hydroxyl group containing and phosphorus containing diesters; (ii) reacting at least one portion of hydroxyl group with a bifunctional phosphorus compound e.g. carboxyl group containing phosphinic acid; (iii) reacting unreacted hydroxyl group with a further unsaturated dicarboxylic acid; and (iv) reacting obtained reaction product with an optionally saturated aliphatic oxirane compound. Phosphorus containing flame retardant obtained by (i) reacting a phosphorus compound, which is 9,10-dihydro-9-oxa-10-phospha-phenanthren-10-oxide or ring-substituted 9,10-dihydro-9-oxa-10-phospha-phenanthren-10-oxide derivatives, with an unsaturated dicarboxylic acid or its anhydride in the presence of a polyvalent alcohol to obtain hydroxyl group containing phosphorus containing diesters; (ii) further reacting at least one portion of hydroxyl group with a bifunctional phosphorus compound from the carboxyl group containing phosphinic acid or their anhydrides or carboxylic acid ester, dicarboxylic acid semiester of polyalkylene glycol phosphonate and/or polyalkylene glycol phosphate; (iii) reacting unreacted hydroxyl group with a further unsaturated dicarboxylic acid or its anhydride; and (iv) reacting obtained reaction product with an optionally saturated aliphatic oxirane compound. Independent claims are included for: (1) a polymerizable composition for the preparation of thermoplastic molded mass comprising 10-40 wt.% of the flame retardant and 60-90 wt.% of at least an olefin unsaturated monomers; (2) a thermoplastic molded mass obtained by copolymerizing the polymerizable composition; (3) a curable synthetic resin composition comprising 10-40 wt.% of the flame retardant and 60-90 wt.% of at least a curable synthetic resin from unsaturated polyester resin and epoxide resin; and (4) a duroplastic molded bodies obtained by curing the synthetic resin composition.
