A new ion-exchange membrane was prepared by blending a copolymer of poly(styrene sulfonic acid-co-N-(2-hydroxyethyl) acrylamide) with poly(vinylidene fluoride). The dissolution of the copolymer into water was prevented by the crosslinked network form

Poly[bis(β-phenoxyethoxy)phosphazene] [PBPEP] had been shown in our previous paper to be a very useful polymer for investigating the crystallization mechanism of polymers, as the crystallization rate of PBPEP is extraordinarily small when isothermal

An almost fully saponified atactic poly(vinyl alcohol) and an atactic poly(vinyl alcohol-block-vinyl acetate) of which degree of saponification is 89 mol % were blended by a solution casting method. The phase structure of the blend film was analyzed

The gelation of aqueous solutions containing syndiotacticity rich poly(vinyl alcohol) (s-PVA) and Congo red was studied. The gelation occurred even at 40°C, different from aqueous solutions containing atactic PVA (a-PVA) and Congo red. The melting p

The properties of poly(vinyl alcohol) (PVA) hydrogels containing saccharides (D-xylose, D-fructose, D-glucose, and maltose) were examined. The effect of the addition of saccharides to PVA hydrogels on their melting temperatures was remarkable when th

A highly syndiotacticity-rich (s-) poly(vinyl alcohol) (PVA) of a 66 s-dyad% [s(66)-PVA] was blended by a solution method with atactic (a-) PVA of a 55 s-dyad% and another s-PVA of a 61 s-dyad%. The s(66)-PVA was shown to be able to produce cocrystal

The properties of solutions for syndiotacticity-rich poly(vinyl alcohol) (s-PVA)/dimethylformamide (DMF)/water systems, the gelation of the s-PVA solutions, and the properties of the dried s-PVA gel films were examined. From the results of the dissol

It was reported in our previous paper that a relatively high-strength and high-modulus drawn poly(vinyl alcohol) (PVA) film could be obtained from aged gel sheet. In this paper, the effect of pressing temperature, at which the original PVA/dimethylsu
