A process for making an alkyl phosphinate polymer having a formula
comprising mixing a phosphinic acid or an alkali metal salt of phosphinic acid, a molecular weight modifier, and a polar solvent to form a mixture, adding an alkyne to the mixture, stirring and adding a free radical initiator solution to the mixture, adding the alkyne until saturation, heating and cooling the mixture, and adding to a metallic compound or protonated nitrogen base. The alkyl phosphinate polymer has high heat resistance and is suitable for use in a flame-retardant composition and flame-retardant polymer molding composition.
制备一种烷基膦酸酯聚合物的方法包括混合膦酸或膦酸的碱金属盐、分子量调节剂和极性溶剂以形成混合物,向混合物中加入炔烃,搅拌并向混合物中加入自由基引发剂溶液,直至饱和,加热冷却混合物,然后加入金属化合物或质子化氮碱基。该烷基膦酸酯聚合物具有高耐热性,适用于阻燃组合物和阻燃聚合物成型组合物。
