SYNTHESIS OF POLYSTYRENE-BLOCK-POLYCAPROLACTAM WITH 1,1-BIS-(1′-NAPHTHYL) ETHYLENE AS A DEACTIVATING AGENT

Received Date: 2 June 1992

The insertion of 1,1-bis (1′-naphthyl) ethylene monomer unit into the active polystyrene chain end greatly decreased the reactivity of the active chain end to the carbonyl group, and allowed the polymeric chain end to react only with the double bond in N-methacryloyl caprolactam, resulting in N-acylcaprolactam functionalized polystyrene in 100% conversion. New diblock copolymer of polystyrene with polycaprolactam was synthesized by direct reaction of the functionalized polymer with caprolactam without adding additional alkali metal or their caprolactam salts.
