E. Ramirez-vargas et al., Morphological and mechanical properties of polypropylene [PP]/poly(ethylene vinyl acetate) [EVA] blends. I. Homopolymer PP/EVA systems, POLYM ENG S, 40(10), 2000, pp. 2241-2250
Morphological and mechanical properties of polypropylene [PP]/poly(ethylene
vinyl acetate) [EVA] blends have been studied. Infrared results using thin
films first indicated a transition toward compatibility between both compo
nents at concentrations above 40% EVA. The transition was verified with dif
ferent experimental techniques and it was associated to morphological chang
es and mechanical properties. The PP/EVA blends were mechanically evaluated
in terms of impact and tensile strength to determine the influence of blen
ding on the performance properties of these materials. Agreement was found
between the transition and the enhancement of both elongation at break and
impact strength.
