Notes:
Blends of erucamide (13-cis-docosenamide) and isotactic poly(propylene) were analyzed by means of dynamic mechanical (at 3, 10, and 30 Hz) and dielectric (at 1, 6, and 20 kHz) techniques. The dependence of tan δ with temperature for each one of the blends has been fitted to Gaussian functions in order to deconvolute the overlapped relaxations. Three relaxations for i-PP, αi-PP, βi-PP, γi-PP, three for erucamide, αERU, βERU, and γERU, and five for their blends have been observed and assigned. They do not vary appreciably with composition, suggesting that the components are incompatible either as globules in the matrix or in the amorphous regions of the spherulites, and/or in their surroundings. © 1997 John Wiley & Sons, Inc.
