| Research Abstract |
The blend films of polybutylene succinate (PBS) and cellulose triacetate (CTA) were prepared by using the solvent-cast technique. Chloroform was used as a co-solvent of PBS and CTA, and titanium tetraisopropoxide (TP) was used as a compatibilizer. The effects of the addition of TP on the structure and hydrolysis behavior of the blend films have been investigated with GPC, FT-IR, 13C-NMR and so on. As results, we have the following conclusions : (I) the addition of TP inhibits the crystallization of PBS molecules in the CTA matrix, (ii) the addition of TP decreases the thermal decomposition temperatures of blend films, (iii) the addition of TP does not influence the mechanical properties of the blend films, and (iv) the addition of TP accelerates the hydrolysis of blend films. (v) the addition of TP accelerates the hydrolysis of blend films, (vi) the addition of TP does not influence the vapor permeation of the blend films, and (vii) TP reacts at the esteric site of PBS and scissors the main chain of PBS.
