Graft Polymerization of Various Monomers onto 6-Nylon in Calcium Chloride-Methanol Solution

Abstract

Graft polymerization of vinyl monomers, such as MA, MMA, St, VAc, or etc., onto 6-nylon in CaC12-MeOH solution was studied in the presence of radical initiators. The graft reaction of monomers proceeds in the presence of unsaturated carboxylic acid, such as AA or MAA. On the other hand, no graft reaction occurs in the absence of unsaturated acids or in the presence of saturated acid, such as propionic acid. The effects of initiators, organic acids, metal salts, and monomers, as well as the graft reaction onto 6-nylon fiber in water were also nvestigated,
