Over the past twenty years or more there has been widespread interest in various kinds of multicomponent polymer systems, including polyblends, block copolymers, and segmented elastomers. More recently, considerable interest has also been focused on questions concerning polymer/polymer compatibility and incompatibility in these systems, and also in related systems such as interpenetrating networks and alloys. Among this diverse group of multicomponent and in some cases multiphase polymers, one that has received perhaps the most overall attention, because of the combination of its great commercial importance and scientific interest, has been the so-called high-impact plastics and resins. Typically, these multiphase polyblends are based on a dispersed, rubbery phase such as polybutadiene which is contained in a glassy, continuous matrix such as polystyrene. The presence of the second, dispersed phase imparts added impact strength, as measured, for example, by an Izod impact apparatus, to the composite above that possessed by the homopolymer polystyrene itself; and it is this enhancement, of course, which leads to the commercial importance of polyblends of this type. In the development of high-impact plastics and the subsequent study of their physical and mechanical properties, a considerable body of information and data has appeared.
