目前，单一材料的性能和使用条件已经不能够满足生产生活所需，为了获得理想

At present, the performance and use conditions of a single material can no longer meet the needs of production and life. In order to obtain the ideal comprehensive performance, different types of polymers are blended by physical or chemical methods to improve the performance of the original polymer or form a New performance polymer blends. This article introduces the research progress of the interaction and compatibility in blends, compatibilization, phase separation of block copolymers and blends, crystallization behavior in blends, and interfacial properties.

At present, the performance and conditions of use of a single material can no longer meet the needs of production and life, in order to obtain the ideal comprehensive performance, different types of polymers are mixed by physical or chemical methods to improve the performance of the original polymer or form a new performance of polymer mix. In this paper, the research progress of interaction and compatible in the common mix, the role of increased capacity, the separation of the segmented conjugation and the common mix, the crystallization behavior in the common mix and the nature of the interface are introduced.

At present, the properties and service conditions of single material can not meet the needs of production and life. In order to obtain ideal comprehensive properties, different kinds of polymers are blended by physical or chemical methods to improve the properties of original polymers or form polymer blends with new properties. In this paper, the research progress of interaction and compatibility, compatibilization, phase separation of block copolymers and blends, crystallization behavior and interfacial properties of blends were introduced.<br>
