Synthesis of aliphatic amidediol and used as a novel mixed plasticizer for thermoplastic starch

In this paper, aliphatic amidediol was synthesized and mixed with glycerol used as a plasticizer for preparing thermoplastic starch (AGPTPS). The yield of aliphatic amidediol was 91%. FT-IR expressed that the mixture of aliphatic amidediol and glycerol formed stronger and stable hydrogen bond with starch molecules compared to the native cornstarch. By scanning electron microscope (SEM) native cornstarch granules were proved to transfer to a homogeneous continuous system. After being stored for a period time at room temperature, the mechanical properties of AGPTPS were also studied. As a mixed plasticizer, aliphatic amidediol and glycerol would be practical to extend TPS application scopes.
