テトラフルオロメタン,パーフル君ロメチルシクロヘキサン,およびパーフルオロトルエンとアンモニアガス混合系のグロー放電重合を行ない,生成物を元素分析, IRおよびESCAスペクトルより検討し,さらに,生成ポリマーの物性について若干の検討を加えた。<br>上記フルオロカーボンのグロー放電重合は,アンモニアガスの混合によって促進される。アンモニアガスの混合によってF成分が脱離し, N成分は主にアミドとしてポリマー中に導入される。これに伴なって表面は疎水性から親水性へと変化する。生成したフィルムのガス透過性は混合したアンモニア濃度に影響を受ける。窒素ガスに対する酸素ガスの透過係数比は2以上となる。

Kusakizome is a collective term of Japanese traditional dyeing technologies using naturally-occuring pigments. For green dyeing of a cloth in Kusakizome , two methods have been mainly utilized : (1) the combination of indigo blue and yellowish flavonoids, and (2) chlorophyl green coupled with a copper salt as a color fixative. We have demonstrated useful methods for green dyeing which features the use of anthocyanin blue with alum mordant under the weak basic condition coordinating with natural yellow pigments. Various anthocyanin-containing plants or flowers could be utilized for the green dyeing and the operative simplicity is highly attractive. Some factors for solidity of the green cloth in the method were also evaluated.

Immobilization of invertase on cross-linked polymers consisting of cellulose and polyethyleneimine (Cell-PEI) and the enzymic activity of immobilized invertase were investigated. Invertase was coupled with Cell-PEI by glutalaldehyde. The amount of invertase coupled was independent of reaction temperature and increased with an increase in invertase concentration. Neutral or weak basic conditions were favorable for the coupling reaction.The optimum pH of invertase activity was shifted to acidic side by the immobilization. The activity at the optimum pH was 26% of that of native invertase. The optimum temperature of invertase activity was little affected by the immobilization. The immobilized invertase was repeatedly used without the activity loss.

The temperature rise of high density polyethylene films during necking was measured with a thermocouple and the generated heat was estimated. The fractions of mechanical work converted into heat were estimated to be 60-86% from the temperatures immediately after necking, and to be 67-90% from the maximum temperatures. Real films showed the fractions lower than 75% because of heat loss and of the formation of new surfaces like cracks. The fraction of heat conversion depended on film thickness, and thin films showed the higher values because of those larger neck propagation speeds.

Methylcellulose attains the water‐solubility by reducing the strong hydrogen‐bonding. The reduction of the hydrogen bonding is achieved by partially substituting hydrophobic methoxy group for hydroxy group in cellulose. However, the substitution gives double‐bladed property to the aqueous methylcellulose, namely, excessive substitution makes again methylcellulose insoluble in water. Therefore, the water‐solubility of methylcellulose is strongly affected by the degree of substitution and moreover the distribution of the substituents. In this study, however, for a commercially available methylcellulose we have modified the cloud point by the addition of various organic salts. Sodium styrene sulfonate (NaSS) showed a strong salting‐in effect, whereas the polymeric NaSS, i.e., sodium polystyrene sulfonate (NaPSS), showed oppositely a salting‐out effect.
