摘要：
Poly(ethylene azelate) (PEAz) was synthesized and its melting behavior was studied with DSC and Step Scan DSC. The equilibrium melting point of PEAz was found 62 degrees C and the heat of fusion of 100% crystalline polymer was estimated at 160 J.g(-1). Polarized light microscopy showed mixed birefringence. From isothermal crystallization DSC study, after self-nucleation, crystallization rates were estimated. The Lauritzen-Hoffman plots showed crystallization regime I to II and II to III transition at 34 and 19 degrees C respectively. Non-isothermal crystallization was studied. The activation energy was calculated applying the isoconversional method of Friedman. Chemical hydrolysis of PEAz was very slow, while enzymatic hydrolysis showed comparable rates with PCL.
