Disclosed is a reactive flame retardant which provides a resin with excellent flame retardance even when it is added in a small amount while being prevented from bleedout. Also disclosed is a flame-retardant resin processed article obtained by using such a reactive flame retardant. An organophosphorus compound represented by the general formula (I) below, wherein at least one or more of X

represent a group containing phosphorus and having a terminal unsaturated group, is used as a reactive flame retardant which is reactive with resins. A flame-retardant resin processed article can be obtained by solidifying the resin composition containing the organophosphorus compound and then reacting it through heating or application of radiation.
揭示了一种具有反应性的阻燃剂,即使在添加量很少的情况下也能为
树脂提供出色的阻燃性能,同时防止渗出。还公开了一种使用这种反应性阻燃剂获得的阻燃
树脂加工制品。一种有机
磷化合物,其表示为下面的一般式(I),其中至少一个或多个X1-X3代表含
磷并具有末端不饱和基团的基团,被用作与
树脂发生反应的反应性阻燃剂。通过固化含有该有机
磷化合物的
树脂组合物,然后通过加热或辐射处理来反应,可以获得阻燃
树脂加工制品。
