Phosphorus containing flame retardants are prepared by a two step process having as essential steps:
1. reacting diorgano organophosphonate with reactant comprising phosphorus oxide reagent to yield a metaphosphate/phosphonate reaction product, and thereafter;
2. reacting the reaction product of step (1) with reactant comprising epoxide to yield poly(oxyorganophosphate/phosphonate) product.
Selected novel poly(oxyorganophosphate/phosphonate) products contain a backbone structure of repeating units represented by the average formula:
wherein m is an integer from 1 to 50; R, R1, and R2 are individually selected from saturated hydrocarbon radical, alkaryl radical, aralkyl radical, and aryl radical; and R3 is:
wherein R4 R5, R6, and R, are individually selected from hydrogen atom, hydrocarbon radical, and halogenated hydrocarbon radical.
Articles and compositions such as textiles and polyurethanes are rendered flame retardant by incorporation of poly(oxyorganophosphate/phosphonate) prepared by the process of the invention particularly products of Formula (I).
含磷阻燃剂是通过两步法制备的,其中两步是关键步骤:
1. 使二甘膦有机膦酸盐与包含氧化磷试剂的反应物反应,生成偏磷酸盐/膦酸盐反应产物,然后;
将步骤(1)的反应产物与包含环氧化物的反应物反应,生成聚(氧有机膦酸盐/膦酸盐)产物。
选定的新型聚(氧有机磷酸酯/膦酸盐)产品含有由平均式表示的重复单元组成的骨架结构:
其中 m 是 1 至 50 的整数;R、R1 和 R2 单独选自饱和烃基、烷芳基、芳烷基和芳基;R3 是:
其中 R4、R5、R6 和 R 分别选自氢原子、烃基和卤代烃基。
通过加入本发明工艺制备的聚(氧有机磷酸酯/膦酸酯),特别是式(I)产品,可使纺织品和聚氨酯等物品和组合物具有阻燃性。
