Introductionls, like liquid crystals, are very significant in the life of contemporary humans because of their very wide usage. The amount of product of plastics in the world increases as 115 x 10. t (in 1994), 121 x 10. t (1995) and 129 x 10. t (1996) compared to the almost constant amount of production of iro

Metallocene Catalyzed Polymerization of Methylmethacrylateortant properties of metallocenes is their catalytic activity for olefin polymerizations . Breslow et al. and Natta et al. first reported the polymerization of ethylene using dicyclopentadienyltitanium dichloride (Cp.TiCl.) activated by an aluminum alkyl, such as diethylaluminum chloride in 1

Polymer Objects: Towards New Polymer Architecturestory, the history of synthetic polymers is quite short, extending over the past 70 years. Synthetic polymers can be exemplified by fibers, gums, and plastics that are nowadays indispensable. Usual polymers are so-called linear macromolecules in which tens of thousands to millions of low-molecular we

Biomimetic Membranesmolecules and energy. Molecular recognition mechanisms and stimuli-responsive mechanisms play important roles in the generation of such functions. Mimics of these functions in material science are interesting both from the academic and practical points of view. There are many approaches to mimic the

Polymeric Membranes for Separatione difference between the two sides of a membrane. In operation, various kinds of substances are separated under low temperature and without phase transition. Therefore, membrane separation is an energy saving process, and can be applied to separations where change of substance quality should be prev
