摘要

This review shortly describes the effects of the basic factors on the morphologyof immiscible polymer blends. The major interest was focused on the effects of viscosity and melt elasticity on the phase inversion point. The possiblity to achieve minor phase continuity was considered as well. Attention was also paid to other factors like compatibilization and spinodal decomposition which are important when examining the minor phase continuity. Several systems exhibiting continuous minor phase are also described. In the second part filler concentration and distribution in polymer matrix was considered on the basis of percolation threshold which was regarded as the critical amount of filler necessary to build up a continuous network. The consideration was made also for filled systems with immiscible polymer blend as the matrix. The effects of several factors such as melt viscosity, surface tension, filler concentration and different surfactants and interfacial agents are discussed.
