Abstract: Disclosed is a foam comprising a matrix and cells included in the matrix. The matrix comprises denatured protein and at least one compound selected from the group consisting of alginic acid, salts thereof, and derivatives of alginic acid.

Abstract: Disclosed is a foaming material composite including a water-soluble polysaccharide having ester linkage or amide linkage, a foaming agent, and a plasticizing agent.

Abstract: A method of decomposing a thermosetting resin by a decomposer comprising the steps of: pre-heating the thermosetting resin up to a pre-heating temperature T0; kneading the pre-heated thermosetting resin together with a decomposer, and concurrently heating a mixture comprising the thermosetting resin and the decomposer up to a kneading temperature T1, thereby allowing a reaction to take place between the decomposer and the thermosetting resin to obtain a kneaded matter wherein the decomposer becomes consumed; and heating the kneaded matter to a maximum temperature T2 to thereby decompose the thermosetting resin; wherein the preheating temperature T0 is not higher than the boiling temperature of the decomposer; the kneading temperature T1 is not lower than the pre-heating temperature T0 but is lower than the thermal decomposition temperature of the thermosetting resin; the maximum temperature T2 is lower than the decomposition temperature of the thermosetting resin; and the pre-heating of the thermosetting resi

Abstract: A copolymer resin composition provided by the process of the present invention is of considerable strength and moldability and is produced by polymerization of a monosaccharide or a polysaccharide that is derived from natural objects and has a hydroxyl group, and a carboxyl group or a salt thereof with a compound having a hydroxyl group and a carboxyl group. The monosaccharide or the polysaccharide serves as a polyfunctional central compound. The copolymer resin composition is obtained through dehydration-polycondensation of (A) at least one selected from the group consisting of a monosaccharide and a polysaccharide having a hydroxyl group, and a carboxyl group or an ion-exchanged carboxyl group; and (B) at least one selected from the group consisting of (b1) hydroxycarboxylic acid, (b2) polyhydroxycarboxylic acid, (b3) a mixture of an aliphatic polyol and an aliphatic polybasic acid, and (b4) an aliphatic polyester obtained by the reaction of an aliphatic polyol with an aliphatic polybasic acid.
