    Abstract: A hydrophilic porous membrane having fine network structure and substantially comprising polypropylene is disclosed, which has on at least one side thereof a surface layer of about the same network structure as that of the inner portion, in which a hydrophilic polymer is chemically bonded to the membrane surface and fine pore surface, and which has an average pore size of 0.1 to 2.0 mu m, a bubble point of up to 2.0 kg/cm , voids of 60 to 85 %, and a water-penetrating amount of 2 ml/min.mmHg.m or more. This membrane is useful as a hydrophilic, plasma-separating membrane. A process for its production and a plasma-separating apparatus containing this membrane in a housing are also disclosed.

    Abstract: PURPOSE:To obtain such a polymer gel system free from diffusion without causing by-reaction which consumes energy such as electrolysis of water and to improve responsibility for the electric field applied, by using a liquid crystal elastomer as a gellating material having compatibility with a low mol.wt. liquid crystal material. CONSTITUTION:This compsn. consists of a low mol.wt. liquid crystal material 3 and a liquid crystal elastomer 1 swollen with the low mol.wt. liquid crystal material 3. The liquid crystal elastomer 1 used has both properties of liquid crystal and rubber and is obtd. by polymn. of a polymerizable low mol.wt. liquid crystal material in the presence of a crosslinking agent. Before voltage is applied, the liquid crystal elastomer 1 is swollen in the low mol.wt. liquid crystal material having orientation of molecules shown in the figure (a). When voltage is applied under a condition of the mesogen 2 of the liquid crystal elastomer and dielectric anisotropy of the low mol.wt. liquid crystal molecules 3 positive, the compsn. is oriented as shown in the figure (b) in such a manner that the direction of the major axis of the liquid crystal molecules is parallel to the electric field.

    Abstract: PURPOSE:To enable the dyeing in excellent resist printing effect by using a resist printing material composed of a film of a heat-sensitive polyacrylamide derivative exhibiting phase-transition between hydrophilic state and hydrophobic state with temperature in the presence of water. CONSTITUTION:A solution composed mainly of a heat-sensitive polyacrylamide derivative (e.g. poly-N-isopropyl acrylamide) exhibiting reversible phase-transition between hydrophilic state and hydrophobic state with temperature is formed in the form of a film of a resist printing material. The film is cut to a prescribed pattern and pasted on a cloth wet with water and the cloth is printed over the resist film and steamed (or dip dyed) at a temperature above the intrinsic phase-transition temperature of the heat-sensitive polymer. Color is developed by this process on the cloth except for the pasted part to attain an excellent resist printing effect leaving a clear white part on the cloth. Both faces of a cloth can easily be dyed in different colors by coloring the other face of the cloth by similar method.
