<p>PROBLEM TO BE SOLVED: To obtain a high-molecular compd. which is decomposable and, when decomposed, gives a recyclable decomposition product by incorporating, into the same, a saccharide-chain high-molecular compd. which has the main chain formed from a saccharide having glucopyranose rings only and other components and to provide a method for decomposing the same. SOLUTION: Pref., the saccharide having a glucopyranose ring only is bonded to other components with an enzymatically decomposable bond, an ester bond, a urethane bond, or a peptide bond, and is pref. an oligosaccharide. Pref. oligosaccharides are maltose, cellobiose, lactose, isomaltose, chitobiose, chitotriose, cellotriose, maltotriose, cellotetraose, chitotetraose, cellopentaose, maltotetraose, maltopentaose, chitopentaose, cellohexaose, chitohexaose, and acetylation products of these oligosaccharides. Pref. other components are dicarboxylic acids.</p> |
