Notes:
Isopropenyldiphenylphosphine oxide (I) and both cis- and trans-n-propenyldiphenylphosphine oxides (II) have been prepared and their structures assigned primarily on the basis of infrared and NMR analyses. Like vinyldiphenylphosphine oxide, these monomers are polymerized sluggishly by free radical catalysts although copolymers with may common vinyl monomers can be prepared. Grignard reagents polymerize (I) very rapidly to low molecular weight products, but the polymerization of II by these catalysts is slower and requires larger amounts of catalyst. Evidence is presented which indicates that in the polymerization of vinyldiphenylphosphine oxide by Grignard reagents molecular weight may be limited by a chain transfer to monomer process.
