POLYMERIC PHOSPHORUS-CONTAINING COMPOSITIONS AND THEIR USE IN HYDROCYANATION, UNSATURATED NITRILE ISOMERIZATION AND HYDROFORMYLATION REACTIONS

摘要

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.
