文摘

Graft polymerization of glycidyl methacrylate (GMA) onto polyethylene fiber was carried out in emulsion solution obtained by dissolving GMA in water with sodium n-dodecyl sulfate (SDS) as a surfactant. GMA micelles diameter was 415 nm at 5 % GMA with 4 % SDS and increased up to 1840 nm at 10 % GMA with 12 % SDS. Degree of grafting (Dg) which was estimated by the weight gain after grafting increased with the increment of GMA concentration in the range 2 to 8 % and slightly reduced at 10 % GMA. The increment in SDS concentration from 4 % to 16 % at 5 % GMA reduced Dg from 120 % to 18 % . In emulsion graft polymerization, Dg was affected by covered area by GMA/SDS micelles on the fiber.
