Water Vapor Permeability of Thermosetting Resin Membranes
熱硬化性樹脂皮膜について,その組成および化学的な構造が皮膜の透湿係数に与える影響を検討した。樹脂としては,ジアリルフタレートプレポリマーとポリ(エチレンマレエート)とのブレンド物,およびポリ(エチレンマレエート)とジアリルフタレートとのグラフト物を用いた。試料樹脂皮膜は,わく張したセロファンを上記プレポリマーを,ベンジルアルコール:メチルイソブチルケトン(1:1)混合溶剤にとかした溶液中へ浸漬し,風乾後焼付けて作った。透湿係数の測定は,カップ法により行なった。透湿係数は,ブレンドした場合には,ジアリルフタレート部分の多くなる程低下し,グラフトした場合には,そのプレポリマーのヨウ素価の大なる程小さくなることがみられた。

WATER SORPTION AND WATER VAPOR PERMEABILITY OF NYLON 4
Equilibrium water sorption on Nylon 4 and diffusion process of water in the polymer were studied. Water sorptive ability of Nylon 4 is lower than that of regenerated cellulose, higher than that of cotton and three times of that of Nylon 6. The temperature dependence of the sorption isotherm is not significant.Diffusion coefficient obtained from the ...

Bio‐Inspired Molecular Events in Poly(Ionic Liquids)
Originating from dipolar and polar inter‐ and intra‐chain interactions of the building blocks, the topologies and morphologies of poly(ionic liquids) (PIL) govern their nano‐ and micro‐processibility. Modulating the interactions of cation‐anion pairs with aliphatic dipolar components enables the tunability of properties, facilitated by “bottom‐up ...

The Water Vapor Permeability of Polycrystalline Fat Barrier Films
The water vapor permeability of fat barrier films has been associated with structural characteristics such as polymorphism, crystal size, and chemical composition, among others. However, no mechanistic models have been proposed to describe this relationship.
