Nonisothermal Crystallization Kinetics and Melting Behavior of Poly(oxyethylene-b-butylene adipate) Ionomers by DSC |
| 초록 |
The crystallization kinetics and melting behavior of poly(oxyethylene-b-butylene adipate) ionomer were investigated by using differential scanning calorimeter (DSC). The Avrami analysis modified by Jeziorny and combination plots developed by Mo could well describe the nonisothermal melt crystallization process of Poly(oxyethylene-b-butylene adipate) ionomers (POBAis) and Poly(oxyethylene-b-butylene adipate)s (POBAs) without ion group. The half time of crystallization decreases, and the Avrami exponents and the rate constants increase with increasing cooling rate. The activation energy based on the Kissinger method and Takhor method was evaluated for nonisothermal crystallization. Thermograms of second heating run are different between ionomer and non-ionomer, indicating that the ion group may affect on the crystal growth. |
