A polymeric, phosphorus-containing composition made by heating, in the presence of an initiator, preferably a free radical initiator, and optionally in the presence of one or more comonomers, at least one substituted phosphonylated 2,2′-dihydroxyl-1,1′-binaphthalene or at least one substituted 2,2′-dihydroxyl-1,1′-biphenylene.
通过在引发剂存在的情况下加热制备的一种含磷聚合物组合物,最好是自由基引发剂,并且在必要时在一个或多个共聚单体的存在下,至少包含一种取代磷酰化的2,2′-二羟基-1,1′-联萘或至少包含一种取代的2,2′-二羟基-1,1′-联苯。
