摘要： This disclosure provides a thermally decomposable binder for which dewaxing can be performed at low temperatures, and an inorganic fine particle-dispersed paste composition comprising this binder. Specifically, the disclosure provides a thermally decomposable binder comprising an aliphatic polycarbonate resin comprising a constituent unit represented by formula (1):

wherein R 1 , R 2 , and R 3 are identical or different, and each represents a hydrogen atom, an alkyl group having 1 to 10 carbon atoms, or an aryl group having 6 to 20 carbon atoms, and n is 1 or 2, and provides an inorganic fine particle-dispersed paste composition comprising this binder.

摘要： A binder resin composition comprising an aliphatic polycarbonate resin represented by the formula (1):

, and an end-capped aliphatic polycarbonate resin represented by the formula (2):

wherein each of X and Y, which may be identical or different, is a group having at least one functional group selected from a carboxy group, an ester group, a carbamate group, a silicate group, an isocyanate group, an ether group, an acetal group, and a halogen atom at its end; and an inorganic particle-dispersed paste composition containing the resin composition. The binder resin composition of the present invention can be used in general molded articles, optical materials such as films, fibers, optical fibers, and optical disks, thermally decomposable materials such as ceramic binders, and lost foam casting, medicinal materials such as drug capsules, additives for biodegradable resins, main components for biodegradable resins, and the like.
