Structural insight into the viscoelastic behaviour of elastomeric polyesters: effect of the nature of fatty acid side chains and the degree of unsaturation
Xinhao Liu, Tanmay Jain, Qianhui Liu, Abraham Joy
Abstract
Increase in unsaturation of fatty acid side chains results in decrease of zero-shear viscosity, degree of entanglement and resilience of polyesters. <italic>Cis</italic> double bonds act as kinks that prevent molecular packing of polymer chains.
