A DYNAMIC INVESTIGATION OF ESTERIFICATION IN BIODEGRADABLE STARCH-BASED POLYMER

摘要

Torque, time, and temperature were simply applied to monitor the dynamic esterification of degradable starch-based polymers reacted by different types of acids and catalyst. The formation of C=O double bond and C-O single bond at the region of around 1710cm~(-1) and 1250cm~(-1) respectively denotes some successful consequence. SEM was furthermore applied to check the compatibility between modified starch and polymer while TGA for the check of starch before and after modification.
