摘要
By direct comparison with dilatometry the use of a differential scanning calorimeter to determine accurate crystallization data from bulk polymers is considered. Fractions of polyethylene are used because of the high temperature dependence of their crystallization rate constants and accordingly the requirement of isothermal crystallization conditions. The accuracy of the temperature settings and the resolution of the instrument in detecting rate of heat changes are described. The requirements of the technique and choice of operating conditions are also described. The principal advantages of the method are that micro samples are required and quantitative kinetic isotherms can be rapidly obtained over a range of temperature. The values of the crystallization rate parameters so determined are discussed. © 1969.
