Abstract
Injected foams obtained from blends with different compositions of isotactic polypropylene, iPP, and two different low density polyethylenes, LDPE, were analyzed by X-Ray diffraction, differential scanning calorimetry, and dynamic mechanical thermal analysis. Most of the results on the blends can be simulated as a weighed addition of the two pure components, indicating practical immiscibility. Some features about the crystallization of the iPP component pointed out inhibition and, consequently, a delay in the development of monoclinic crystalline entities.
