Abstract
Ternary mixtures of isotactic polypropylene (iPP), high density polyet hylene (HDPE) and hydrogenated oligo(cyclopentadiene) (HOCP) commercia l products were prepared by melt mixing. The crystallization behaviour of iPP/HDPE and (iPP/HDPE)/HOCP systems were compared. It was shown t hat the ternary system separated in two binary systems. The presence o f HOCP modified the morphology of iPP and HDPE phases. The polyolefins nucleation and crystal growth rates decreased due to the diluent effe ct of the oligomer. HDPE showed higher compatibility with HOCP than iP P.
