Title:
POLYMERIC PHOSPHORUS-CONTAINING COMPOSITIONS AND THEIR USE IN HYDROCYANATION, UNSATURATED NITRILE ISOMERIZATION AND HYDROFORMYLATION REACTIONS
Document Type and Number:
WIPO Patent Application WO2003045552
Kind Code:
A3
Abstract:
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 -biphenylene or at least one ethylenically substituted 2,2'-dihydroxyl-1,1'-biphenylene or -binaphthalene, with subsequent phosphonylation. Alternatively, an aryl phosphorochloridite containing at least one (meth)acrylate group is polymerized and subsequently coupled with a 2,2'-dihydroxyl-1,1'diphenylene or -binaphthalene. These polymers and the corresponding phosphonylated 2,2'dihydroxyl-1,1'-binaphthalene or biphenylene monomers may be combined with a group VIII metal to form catalysts for hydrocyanation, hydroformylation or unsaturated nitrile isomerization.
