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 -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.
摘要:
The present invention relates to polymeric charge transport compositions. The invention further relates to electronic devices in which there is at least one active layer comprising such charge transport compositions.
摘要:
Hydrocyanation reactions employing multidentate phosphite ligands and multidentate phosphite ligands are disclosed. The ligands have phenyl containing substituents attached to the ortho position of the terminal phenol group and/or attached to the ortho position of the bridging group. Catalyst compositions having such ligands achieve 97 % or greater distribution in hydrocyanation.
