摘要： PROBLEM TO BE SOLVED: To provide a method capable of producing a regenerated resin from a large amount of urethane resin decomposed material by efficiently removing water generated by reaction of a urethane resin decomposition product when producing the regenerated resin by using the urethane decomposition product.
SOLUTION: The method for producing the regenerated resin comprises a step for carrying out mixing and reacting while bringing a resin composition into contact with a gas in a state in which resin thickness of the resin composition is controlled to ≤10 cm. The resin composition is obtained by reacting a resin decomposed material obtained by chemically decomposing a urethane resin with a compound having two or more carboxy groups or a compound having one carboxy group and one or more unsaturated carbon bonds. The regenerated resin can readily be produced by the method. Similar effect is obtained by adding a kneading auxiliary material having ≤10 mm average particle diameter to the mixture and melting and kneading the above mixture with the kneading auxiliary material.

摘要： PROBLEM TO BE SOLVED: To provide a reclaimed resin using a decomposition product of a urethane resin and a process for producing the reclaimed resin and to provide a reclaimed urethane as a urethane resin composition having good decomposability.
SOLUTION: In the process for synthesizing a reclaimed urethane from a decomposition product of a urethane, the reclaimed urethane is synthesized by a two-step reaction consisting of the first reaction for preparing a prepolymer having an isocyanate at an end thereof as an isocyanate component to be reacted with the decomposition product or synthesizing a prepolymer from the reaction of the decomposition product and an isocyanate and the second reaction for synthesizing a urethane resin from the prepolymer. As a result, urea bonds are inhibited from being densely formed in the prepolymer and the bonds difficult to be decomposed can be readily dispersed. Furthermore, the structure in the reclaimed resin can be controlled to provide for uniformity in the components and the molecular weight of a secondary decomposition product into which the reclaimed resin is re-decomposed, whereby the reclaimed urethane results in a urethane resin composition which can be easily decomposed for recycle use.
