Abstract
Vinyl monomers are polymerized in the presence of bi(phosphine oxides) and bi(phosphine sulfides) which can function as photoinitiators and chain transfer agents in the polymerization of vinyl monomers. The incorporation of such organo-phosphorous compounds into such polymers either as an integral part thereof, or as an admixture, results in improved thermal stability of the polymers.
