Multiphase polymer blends are important in the polymer industry. Most commercial blends consist of two main polymers combined with a third, compatibilizing polymer, typically a graft or block copolymer. The most common examples are those involving the impact modification of a brittle thermoplastic by the microdispersion of a rubber into the matrix. Recently, a model of ternary polymer blend has provided a wealth of morphologies for examination. Even though this model can give an excellent basis for the design of a polymer blend, experimental verification is necessary. A correlation of blend properties such as impact strength with blend morphology must also be made. The focus is to confirm the predicted morphologies in binary and ternary blends using HVEM.
