ISOTHERMAL CRYSTALLIZATION AND MELTING OF ETHYLENE OXIDEPROPYLENE OXIDE COPOLYMER
Abstract:
The kinetics of isothermal crystallization of ethylene oxide and propylene oxide copolymers has been investigated by differential scanning calorimetry. The values of Avrami exponent n were found as 1.8~2.4. The nueleanlon process in crystallization temperature takes place according to regime Ⅱ The eqilibrium melting points of EO/PO copolymer decrease with increasing content of PO. The crystal growtb rate Gis in dependence on the composition of the copolymer and the crystalization temparature.
