Poly[acrylonitrile-co-(methyl acrylate)-co-(itaconic acid)]: effects of MA contents on char-yielding and thermal behaviors |
| 초록 |
AN/MA/IA (poly(acrylonitrile/methyl acrylate/itaconic acid)) copolymers were synthesized as a carbon fiber precursor. The effects of methyl acrylate (MA) incorporation (0-15 mol%) on the glass transition, melting behaviors, and the peak temperature of the stabilization exotherm in acrylonitrile (AN) based copolymers were studied. Increasing in concentration of MA retarded the overall polymerization rate and led a decrease in the polymer molecular weight. Two kinds of polymerization methods were used; solution polymerization and microwave polymerization. It was found that the crystallization temperature become lower with higher MA content in copolymers, and it could be confirmed by Tg from DSC. Char yields of the copolymers were determined by thermogravimetric analysis (TGA). |
