Effects of Addition of Titanium Tetraisopropoxide on Structure and Hydrolysis Behavior of Poly(butylene succinate)/Cellulose Acetate Blends.

Abstract

The blend films of poly(butylene succinate) (PBS) and cellulose triacetate were prepared by using the solvent-cast technique. Titanium tetraisopropoxide (TP) was further added to the blend during the blend process. 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 a result, we have the following conclusions: (i) the addition of TP accelerates the hydrolysis of blend films, (ii) the addition of TP does not influence the water vapor permeation of the blend films, and (iii) TP reacts with the esteric site of PBS and scissors the main chain of PBS
