20.Fully biodegradable poly(3-hydroxybutyrate-co-hydroxyvalerate)/poly(ethylene succinate) blends: Phase behavior, crystallization and mechanical properties. Miao L, Qiu Z,* Yang W, Ikehara T. Reactive and Functional Polymers 2008; 68 (2): 446-457
Abstract
Poly(3-hydroxybutyrate-co-hydroxyvalerate) (PHBV) and poly(ethylene succinate) (PES) are both biodegradable semicrystalline polyesters. Phase behavior, crystal structure, crystallization kinetics, and mechanical properties of fully biodegradable PHBV/PES blends were investigated by differential scanning calorimetry (DSC), polarizing optical microscopy (POM), wide angle X-ray diffraction ...
