摘要: A method for fractionating crystalline copolymers to determine solubility distribution as a function of temperature. Fractionation is conducted by passing solvent through column containing the crystallized copolymer at an increasing temperature from 6° C. about 120° The polymer solution exiting analyzed infrared spectroscopy or NMR composition copolymer.
