Effect of molecular weight and temperature on the isothermal crystallization of poly(oxetane) Poly(oxetane) poly(oxacyclobutane) isothermal crystallization bulk crystallization crystallization temperature coefficient Poly(oxetane) poly(oxacyclobutane) isothermal crystallization bulk crystallization crystallization temperature coefficient Abstract Poly(oxetane) fractions ranging in number-average molecular weights from 7800 to 157000 have been isothermally crystallized in the temperature range from −50 to 19 , using dilatometric and calorimetric techniques. In both cases, reproducible isotherms were obtained with an Avrami exponent equal to three. The crystallization rate against crystallization temperature presents a maximum at −30 . The level of crystallinity changes with molecular weight and the influence of this parameter on the rate of crystallization is pronounced. The crystallization temperature coefficient was studied using nucleation theory and it was found an slight increase in the basal interfacial free energy for the lowest molecular weight fraction. For the analysis of the temperature coefficient at the higher undercoolings, different approximations for the free energy of fusion and the transport term have been considered. The conclusion of this analysis is that, independently of these approximations, the obtained temperature coefficients are the same. 1435-1536 14351536 Springer |
