| 中文摘要 | the hydrogen bonding and crystallization of a biodegradable poly(ester urethane) copolymer based on poly(l-lactide) (plla) as the soft segment were investigated by ftir. on slow cooling from melt, the onset and the progress of the crystallization of the urethane hard segments were correlated to the position, width, and relative intensity of the hydrogen-bonded n-h stretching band. the interconversion between the "free" and hydrogen-bonded n-h and c=o groups in the urethane units in the process was also revealed by 2d correlation analysis of the ftir data. the crystallization of the plla soft segments was monitored by the ester c=o stretching and the skeletal vibrations. it was revealed that the plla crystallization was restricted by the phase separation and the urethane crystallization, and at cooling rates of 10 degrees c/min or higher, the crystallization of the plla soft segments was prohibited. |
