Emulsion grafting of vinyl acetate onto preirradiated poly(3-hydroxybutyrate) film

Wada, Yuki*; Tamada, Masao; Seko, Noriaki; Mitomo, Hiroshi*

Vinyl acetate (VAc) was grafted onto poly(3-hydroxybutyrate) (PHB) film by preirradiation method. Grafting reactions were carried out in a VAc/water/surfactant emulsion, VAc/water, and VAc/methanol systems. For emulsion grafting, Nonion L-4 was ascertained to be the optimum surfactant with regard to the stability of a single emulsion layer. The emulsion with a 10:1 (w/w) ratio of VAc and surfactant yielded the highest degree of grafting (Xg) 23%. The grafting efficiency in the emulsion and the water and methanol solvent were evaluated. The results indicated that the grafting efficiency of the emulsion is 100 times that of VAc/methanol when the same 2 wt% VAc was used in the grafting reaction.
