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 ethylenically substituted phosphonylated 2,2'-dihydroxyl-1,1'-binaphthalene or at least one ethylenically substituted 2,2'-dihydroxyl-1,1'-biphenylene.
These polymers may be combined with a group VIII metal to form catalysts for hydrocyanation, hydroformylation or unsaturated nitrile isomerization.
一种含磷聚合物组合物,是在一种引发剂(最好是自由基引发剂)的存在下,以及在一种或多种共聚单体的存在下,通过加热至少一种乙烯取代的膦酰化 2,2'-二羟基-1,1'-联萘或至少一种乙烯取代的 2,2'-二羟基-1,1'-联苯而制成。
这些聚合物可与第八族金属结合,形成氢氰化、氢甲酰化或不饱和腈异构化催化剂。
