Paper Title:
Preparation and Characterization of Polylactic Acid/Acetate Starch Blends with Tetrabutyl Titanate
  Abstract

In order to reduce the cost of the polylactic acid (PLLA) material and to improve its flexibility to expand the application of PLA-based plastic, a series of PLLA/SA blends with tetrabutyl titanate (Ti(OBu)4) used as compatibilizer were prepared in the presence of 10% triethyl citrate (TEC) as plasticizer. It was investigated the effect of the compatibilizer and its content on the mechanical properties, structure and morphologies, heat-resistant performance, melt flow rate, and water-resistant performance and other implications of blends. The results showed that: adding the compatibilizer Ti(OBu)4 could significantly improve the compatibility of PLLA and SA, the mechanical properties and thermal stability of the blends were increased, while melt flow rate and water absorption were decreased. When the content of compatibilizer Ti(OBu)4 was 8 wt%, PLA/SA blends(75/25 wt%) had the best overall performance.
