Direct Polycondensation Reaction Using Polymeric Triphenylphosphine as an Initiator

Triphenylphosphine which is known as an effective initiator for direct polycondensation, was immobilized into polymers by polymerizing and copolymerizing with diphenylstyrylphosphine. Copolymerization behavior of diphenylstyrylphosphine with 4-vinylpyridine was analyzed. Polymeric triphenylphosphine could initiate the direct polycondensation to form either polyamide or polyester and a recycling system for the regeneration of triphenylphosphine moiety was proposed.
