    Abstract: Disclosed are a polymer gel in which a phase transition occurs due to a stimulus, a method of manufacturing such a polymer gel, and an actuator which employs such a polymer gel. The polymer gel which is formed by polymerizing monomers at a temperature equal to or less than a phase transition temperature of the resultant polymer gel and separating and/or classifying the polymer gel into fractions according to its size at a temperature equal to or greater than the phase transition temperature thereof. Alternatively, the polymer gel is separated and/or classified into fractions by adding a low molecular weight compound that can dissolve and swell the polymer gel to separate the polymer gel into fractions based upon a difference in dissolving rate or swelling rate. Alternatively separation and/or classification of the polymer gel is performed by a combination of the above-described two methods. In consequence, the resultant polymer gel has an average particle size ranging from 0.1 mu m to 100 mu m, and exhibits standard deviation of within 25 % of the average particle size. The width of the phase transition peak of the resultant polymer gel as measured by DSC at a heating rate of 1 DEG C/min is within 10 DEG C.

    Abstract: An optical device is provided which comprises a liquid layer containing a liquid-absorbable and releasable polymer that absorbs and releases a liquid under the action of an electric field and at least one pair of electrodes holding the liquid layer therebetween. The liquid may be colored, and alternatively the liquid-absorbable and releasable polymer may be colored.

    Abstract: A metal-containing composition contains an organic acid group, a transition metal, an alcohol amine, and water. The alcohol amine is preferably expressed by chemical formula (1): NHmR1n(R2OH)3-m-n (1) where R1 is an alkyl group having 1 to 4 carbon atoms, R2 is an alkyl carbon chain having 1 to 4 carbon atoms and m and n are integers of 0 to 2 that satisfy the relationship of (m+n)
