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 <i>in situ</i>-formed copolymer, the morphology could be tuned up; i.e., the size of dispersed particles can be reduced down to sub-μm to optimize the material properties. This may be a commonly accepted story for the ambiguous but convenient term "<i>compatibilization</i>". Another interfacial behavior recently found is the pull-out of the <i>in situ</i>-formed copolymer by the external shear forces. It renders a new approach for the 10nm morphology control in reactive blending. Such interfacial aspects are successfully applied for the materials design; e.g., super-tough polyamide, high-temperature polyamide alloy for Pb-free solder, high-temperature poly(phenylene ether) alloy, and non-viscoelasic nylon alloy. The dynamic vulcanization is a unique reactive blending which leads to a two-phase material consisting of the crosslinked rubber particles and a matrix of thermoplastic polymer. Strain recovery mechanism of the two-phase material is discussed.

In order to elucidate the degradation behavior of NBR caused by high concentration chlorine water, NBR samples corroded in 200ppm chlorine water and in pure water were analyzed by means of EPMA, FT-IR and XPS. The degradation process of the NBR corroded in high concentration chlorine water is considered as follows: (1) an α-H of the butadiene double bond in NBR molecule is subject to substitution by chlorine; (2) the chlorinated NBR abstracts an α-H in another NBR molecule to cause the elimination of HCl, which generates polymer radicals; (3) the polymer radicals thus produced add to polybutadiene double-bonds in the other NBR. It is concluded that residual chlorine reacts with NBR by chlorination and oxidation mechanisms and that these reactions lead to hardening and degradation of NBR through the increase in the crosslinking density.

When international exhibitions faced difficulties, the EXPO 2005 was succeeded in showing the continuous significance and a new model for international exhibitions or world fares. In order to emphasize and deepen the EXPO's theme "Nature's Wisdom" toward solving global problems and to stir citizens to action, a variety of experimental projects were conducted from four viewpoints: application of cutting-edge technologies; adoption of new social systems; participation by NGOs and citizens; sharing of diverse cultures and values. These experiments were deeply interconnected and served as a model for sustainable society. The EXPO 2005, which had a major impact on the mindset and behavior of over 22 million visitors, particularly young people, earned an international reputation as a "leading project" of the United Nations Decade of Education for Sustainable Development from 2005 to 2014, which was proposed during the World Summit on Sustainable Development held in Johannesburg, South Africa, and adopted by the UN General Assembly in 2002. As a part of international exhibition movement, the EXPO 2005 is communicating its concepts and achievements at every opportunity in the international arena in order to realize the aim of contributing to the solution of global issues.
