Experiments were commenced for resolving the correlation among the imposed cooling conditions, the formed matrix crystalline morphology, and the coalescence of the dispersed phase particles. Confirmation of the profound effect of the PP crystallization on the coalescence of EPR particles was undoubtedly obtained. Thorough discussion regarding the observed effects, encompassing the potential rejection or engulfing of the dispersed phase particles by the growing crystallites, was undertaken.
