The tire wear tests were performed for rubber compounds with different physical properties on the different road surface temperature using the same vehicle. It is clear that the temperature dependence of wear resistance were different for the different rubber compounds. The wear resistance W is found to be scaled using the fracture energy F (MJ/m3) and the storage modulus E* (MPa) for the rubber compound as follows:W = c(Fa / E*b)(a, b, c=the constant number)Temperature dependence of wear resistance is considered to be caused by the different contribution of F and E* values.

As a general introduction to anionic polymerization, this paper will review the categorization of anionic initiators and vinyl monomers according to Q-e values, the nature of carbanions in solution, especially their interaction with counter ions, the controlling of stereochemistry from 1, 3-diene and alkyl methacrylate polymerizations, and the basics of ring-opening polymerization. Vinyl monomers are categorized into four groups according to Q-e values. The anionic polymerizable monomers with higher Q values than 0.2 depend on their e values relating to the electron density on vinyl groups. The polymerization of high reactive monomers can be initiated with weak nucleophiles, while strong nucleophiles are required to initiate the polymerization of low reactive monomers. On the other hand, the relationship between reactivities of monomers and their active chain ends is basically inverse order. In order to understand the kinetics and mechanisms of anionic polymerization, the equilibriums among of the contact ion pair, the solvent separated ion pair, and free ion are discussed in terms of the reactivity of polystyryl anions. The dependence of stereochemistry of 1, 3-diene monomer and alkyl methacrylate polymerizations on the counter cation, solvent, and additive is described.

Homogeneous catalysis promoted by transition metal complexes such as hydrometallation, carbonylation, Wacker oxidation, oxidative coupling reaction are described. Mechanistic aspects of these catalytic reactions are discussed on the basis of the fundamental reaction patterns of organotransiton metal complexes such as ligand dissociation and association, oxidative addition and reductive elimination, insertion and elimination, and reactions of the coordinated substrates.

The adhesion of L929 fibroblast on polymer bilayers composed of a glassy polystyrene (PS) prepared on the top of a rubbery polyisoprene (PI) was examined. Since the top PS layer is not built on a glassy foundation, the system becomes mechanically unstable with decreasing thickness of the PS layer. When the PS film was thinner than 25 nm,the number of cells adhered to the surface decreased and the cells could not be well spread. Fluorescence microscopic observations revealed that the formation of F-actin filaments in cells attached to the bilayers was more pronounced with a thicker PS film than with a thinner one. On the other hand, the thickness dependence of the cell adhesion was not observed for the PS monolayer films. Taking into account that the amount of adsorbed protein molecules was independent of the PS layer thickness of the bilayer films, our results indicate that cells, unlike protein molecules,could sense mechanical properties derived from the deeper region of the scaffold.

Fractionation technique is very significant for the polymer analysis. Several methods were proposed, SEC(Size Exclusion Chromatography), FFF(Field Flow Fractionation), Electrophoresis, Hydrodynamic Chromatography, MTF (Molecular Topology Fractionation), and so on. In these methods SEC is the most general. This report reviews about concepts of separation mechanism, sources of analytical error, detectors, and analysis examples of SEC.

Carbon nanotube (CNT) was found in 1991 by Dr. Iijima, and it has attracted wide attention because of its high mechanical properties along with high electrical and thermal conductivities. However, practical application of carbon nanotube has not been achieved yet. In this article, I repot promising applications of CNT and rubber composite such as high thermal conductive flexible sheet (TIM), stretchable electric wire for devices, high wear resistant material and high thermal durable materials for shielding field. Furthermore, I also report the importance of CNT dispersion for getting high performance the CNT and rubber composite. Just after the synthesis, CNTs form bundled structure. To derive the structural advantage of CNT for filler, de-bundling is important.

Natural rubber (NR) is polyisoprene with 100% of cis-1,4 structure on main chain. NR is a natural resource derived from a tropical tree called Hevea brasiliensis (para rubber tree) that produces latex. NR is an industrial raw material, and global NR production and consumption are about 12 million ton per year (2014) which are about 40% in total rubber usage. Since NR shows superior physical properties such as break strength or durability comparing with synthetic rubber, NR demand is expected to rise in the future. In this review, we describe the present state, trend of new research and development of NR.
