Thermal transitions of ethylene-vinyl chloride copolymers.
01 January 1985
Differential Scanning Calorimetry (DSC) measurements were performed on a series of ethylene-vinyl chloride (E-V) copolymers for the purpose of studying the dependence of their thermal transitions upon their microstructure. The method of preparation, via reductive dechlorination of poly(vinyl chloride) with tributyltin hydride, resulted in a series of E-V copolymers differing only in comonomer content, sequence distribution and stereoregularity of adjacent -V- units. Chain length distribution and chain branching frequencies were identical for each member of the series.
