第1報で開発した膨潤圧縮による架橋構造解析法の応用として, 架橋形態と諸物性との相関を求めた.1) モデルサンプルの架橋構造と疲労の関係より, ポリスルフィド網目(νP)が多く, モノスルフィド網目(νM)が少ないほど, 疲労寿命がアップするというクリアーな関係が得られた.2) モデルサンプルの熱老化と架橋構造の関係より, 熱老化とともにνPが減少, νMの増加を生じるが, 温度上昇とともにこの変化が規則的に顕著になる.3) 1)と2)の結果を用いて, 防振ゴム実走品の熱履歴を推定することが可能となり, 故障解析に有力な手法となった.

Pyrolysis High-Resolution Gas Chromatography equipped with a Doubleshot Pyrolyzer and a metal capillary column were used in order to identify components of polyurethanes. Polymer glycols used are PTMG, PPG, PEA, PBA, PMPA, PCL and PMVL. TDI, HDI, NDI and MDI as diisocyanates and BD, MOCA, TMP, EDA and HMDA as chain extenders were used. The pyrograms of polyurethanes were compared with the referential pyrograms of polymer glycols, diisocyanates and chain extenders as raw materials in detail. These results showed that the main constituents as raw materials can be identified easily by means of pattern analyses of the pyrograms of polyurethanes.

Wide-ranging polymeric materials are commonly used in spacecraft to meet numerous system design requirements. The tolerance of such polymeric materials against the space environment, e.g. vacuum, ultraviolet rays, radiation, atomic oxygen, etc. must be evaluated, because this environment is a known threat for materials, especially polymers. JAXA has been striving to evaluate the tolerance of polymeric materials in the space environment through both ground tests and space exposure experiments, which allows engineers in the space industry to obtain material data detailing tolerance against the space environment. This article introduces the space environment and its effect on polymeric materials, examples of damage to materials in orbit, and the evaluation capabilities for polymeric materials to be used in space at the Tsukuba Space Center, JAXA.

Nowadays, wide variety of rubber hoses is adopted in car with different construction, inner diameter and length, etc. As manifold fluids flow inside those hoses, wide variety of rubber material is utilized. Due to recent trend towards environmental protection, drastic change is expected in hose performance, especially of fuel and air conditioning hose. As for air conditioning hose, how to hold both flexibility and gas barrier performance is utmost concern. In this paper will be reported a recently tackled new approach for providing flexible high gas-barrier rubber materials by applying adsorption phenomena of currently used refrigerant, R-134a, to tetramethylammonium-treated mica. Also trend of future refrigerants will be discussed finally.

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-μm to optimize the material properties. This may be a commonly accepted story for the ambiguous but convenient term "compatibilization". Another interfacial behavior recently found is the pull-out of the in situ-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.
