Polymer Blends: Principles and Applications Part 3. Polymer-Polymer Interface and Reactive Blending Takashi INOUE Department of Polymer Science and Engineering, Yamagata University Nippon Gomu Kyokaishi,(2005),78(12),461-466 General Review in Japanese Abstract Theoretical aspects of polymer-polymer interface are discussed. The interfacial thickness, the interfacial tension, and the adhesive strength are described as a function of the interaction parameter and the molecular weights of component polymers. When both component polymers have reactive sites, the coupling reaction takes place at the interface and the block or graft copolymers are formed. Melt-mixing of such reactive system is called "reactive blending" and "reactive processing". By an emulsifying effect of the in situ-formed copolymer, the morphology could be tuned up; i.e., the size of dispersed particles can be reduced down to sub- ![]() Keywords: Polymer-polymer interface, Interfacial thickness, Adhesive strength, Block copolymer, Graft copolymer, Compatibilization, Reactive blending, Reactive processing, Thermoplastic elastomer, Rubber-toughened plastics |
