Different quantitative approaches enabling the determination of the basic parameters of polymer crystallization were applied to characterize the isothermal and non-isothermal crystallization of homo- and MAH-modified PP in the presence of glass and carbon fibers. Depending on the type of surface treatment and the sur- face morphology, the fibers were shown to exhibit different nucleation effects, which further influenced the course of the crystallization process. The results ob- tained by DSC and POM were evaluated using the induction time approach, interfa- cial energy parameters method, as well as the method for determination of the work of heterogeneous and homogeneous nucleation in polymer systems with additives.
