Van Gurp-Palmen Plot of Loss Angle Versus Complex Modulus

3 Van Gurp-Palmen Plot of Loss Angle Versus Complex Modulus 

Several techniques have been proposed to estimate the level of long-chain branching in randomly branched polymers, but these are only useful within given families of closely-related materials. 

Cole-Cole plots are generated by plotting one frequency-dependent linear property versus another. These have no fundamental significance but have been used to test for time-temperature superposability and as the basis for qualitative assessments of polydispersity and long-chain branching.
