Abstract
In the present study, degradation properties of the polymer blends of poly (lactide) (PLA) and poly (butylenes succinate) (PBSU) with different mixed fractions were investigated. PLA/PBSU (80/20) was exhibited highest water absorption during hydrolysis tests, while biodegradation rate was increased in PLA/PBSU (20/80, Non-Annealing) on soil burial. Tensile tests were conducted on the blends after 0, 8 and 16weeks degradation tests to evaluate the variation in Young's modulus and the tensile strength. Tensile strength of PLA/PBSU (50/50, 20/80 and 0/100, Non-Annealing) and all annealing specimen were sensitive to hydrolysis degradation.
