New Thermal Features of Ethylene-based Polyolefins with Different Chain Architectures as Investigated by Step Scan Differential Scanning Calorimetry Method

doi:10.7503/cjcu20190109

Abstract

Abstract: Several selected commercial polyethylene-based polyolefins with different chain architectures were studied by step scan differential scanning calorimetry(DSC) method. It is found that the temperature dependence of heat capacity is the same for all the polyolefins with different chain architectures in equilibrium liquid state; the heat capacity in stable crystalline state at very low temperature is also very close regardless the variation of chain architectures. While in melting temperature range the heat capacity is very sensitive to the chain architectures, which is ascribed as the branching chains in the crystalline structures of polyethylene far below the main melting peak temperature range of polyolefins. In the step scan DSC of time-heat flow curves, low density polyethylene(LDPE) showed unique melting-recrystallizing behavior, possibly due to the relief of restrained segments between crosslinking points during melting process.

Key words: Polyethylene-based polyolefin, Polymer chain architecture, Thermal property, Absolute heat capacity, Step scan differential scanning calorimetry
