Multiphase and multicomponent polymers have became a very important research field in polymer science and engineering. A new and comprehensive materials can be acheived through blending different polymers by physical or chemical blending technique. At present, at least 80% polymer materials occured in blend form in polymer application field. Many enterprises and research units show a lot of interest in this field. In this course, Chapter 1 introduced the object and meaningness of multiphase and multicomponent polymer materials. The history and future of multiphase and multicomponent were also introdued in Chapter 1. In Chapter 2, the character of compatibility, compatibility theory and its decision method were discussed from the point of compatibility of different polymers. In Chapter 3, the basic structure of multiphase and multicomponent was introduced. There are three basic structures for multiphase and multicomponent. The interface of polymer blend was introduced from the points of formation process, character and effect on compatibility. The effect of compatibility, heat history and rheology history on the structure of polymer blend was discussed. The technique for analysis phase structure was also introduced in this chapter. In Chapter 4, the properties of multiphase and multicomponent was introduced. It give out the relationship of polymer blends with single component. The toughening mechanism was the important part in this course, the history and theory of thoughening mechanism was introduce in this chapter. The craze and shear yielding behavior occured during deformation of polymer matierials. The other toughening mechanism was also introduce in this chapter. The rheology and other properties of multiphase and multicompoent polymer materials were introduced in Chapter 5. The properties include percolation properties, heat properties and electrical properties, and so on. The preparation method and preparation machine were introduced in Chapter 6. The preparation method include physical and chemical method. Physical method include powder mixing, melt mixing, solution mixing and emulsion mixing. Chemical method include graft compolymerization and IPN method. In the same time, the principle of blending process was give out. The blending process include distribution and dispersion process through blending and shearing. The compatibilization method and principle was introduced in Chapter 7. The compatibilization is a very important step for incompatibile blend. Compatibilizer include non-reaction type and reaction type, their main mechanism is emulsifying effect and chemical bonding, respectively. The bonding strength of interface increased and phase domain decreased after compatiblization. The properties and blending examples of normal palstics and engineering plastics were introduce in Chapter 9. At last, reaction blending technique was discussed.
