    Abstract: A fungicidal and bactericidal method of imparting fungicidal and bactericidal properties to an article by coating or impregnating the article with a solution of a quaternary ammonium salt of alginic acid or carboxymethyl cellulose (which is insoluble or sparingly soluble in water) in an organic solvent and thereafter removing the solvent from the article.

    Abstract: Glucan derivatives (such as cellulose acylate derivatives) which are useful as thermoplastics and which are remarkably reduced in moisture absorption and are excellent in compatibility with plasticizers and solvent solubility. Specifically, a glucan derivative composed of glucan (such as cellulose) and acyl groups and a graft chain made from at least one graft component selected from among lactones and oxycarboxylic acids which are bonded to glucose units of the glucan, wherein the hydroxyl group of the graft chain is blocked with a protecting group. The graft chain may be made from C4-16 lactone or the like and the hydroxyl group of the graft chain may be blocked with acyl (e.g., C2-8 alkylcarbonyl such as acetyl). The average degree of substitution with acyl may be about 1 to 2.99, and the average degree of substitution with the graft chain may be about 0.01 to 2.

    Abstract: A glucan derivative (e.g., a cellulose acylate derivative) which is useful for a thermoplastic resin, is inhibited in hygroscopicity at a high level and is excellent in compatibility with a plasticizer or solubility in a solvent is provided. In the glucan derivative which comprises an acyl group and a graft chain formed from at least one graft component selected from a lactone and a hydroxycarboxylic acid, each bonding to a glucose unit of a glucan (e.g., a cellulose) constituting the glucan derivative, a hydroxyl group in the graft chain is protected with a protecting group. The graft chain may be formed from a C 4-16 lactone. The hydroxyl group in the graft chain may be protected with an acyl group (e.g., a C 2-8 alkylcarbonyl group such as acetyl group). The degree of substitution of the acyl group may be from 1 to 2.99, and the degree of substitution of the graft chain may be from 0.01 to 2.
