Graft Copolymers Prepared by Ethoxylation of Polyamide 12 and Poly(ethylene-co-vinyl alcohol)
(1998) In Journal of Polymer Science. Part A, Polymer Chemistry 36(5). p.803-811- Abstract
- Graft copolymers consisting of polyamide 12 or poly(ethylene-co-vinyl alcohol) as backbone polymers and side chains of poly(ethylene oxide) have been synthesized. The amide and hydroxyl groups of the backbone polymers were used as initiation sites for the polymerization of ethylene oxide (EO). Potassium tert-butoxide was used for ionization of the active groups, and the polymerization of EO was carried out in dimethyl sulfoxide. The graft copolymers were characterized with respect to molecular weight and composition using elemental analysis, H-1-NMR, gel permeation chromatography, and FTIR. The size of the side chains varied between 300 and 1000 g/mol. Thermal properties were examined by DSC. The graft copolymers showed increasing... (More)

The graft copolymers showed increasing crystallinity and increasing melt temperature with increasing molecular weight of the side chains. (Less)
