摘要：
An optical polythiourethane thermosetting system based on a 4-mercaptomethyl-3,6-dithia-1,8-octanedithiol and a m-xylylenediisocyanate has been studied. The solid-state isothermal cure reaction was followed by FTIR spectroscopy in the temperature range of 80-120 degrees C. Kinetic and thermodynamic parameters were calculated using normalized conversion curves.
