Title:
RESIN COMPOSITION AND METHOD FOR PRODUCING THE SAME
Document Type and Number:
Japanese Patent JP3880950
Kind Code:
B2
Abstract:
PROBLEM TO BE SOLVED: To provide a resin composition capable of simply producing a regenerated resin excellent in performance by avoiding such reaction that an amine component contained in a decomposed material acts as a catalyst and to provide a method for producing the composition.
SOLUTION: The resin composition is obtained by carrying out addition reaction of a compound having an unsaturated carbon bond with a decomposed material of urethane resin obtained by chemically decomposing the urethane resin or decomposing the urethane resin by using the compound having the unsaturated carbon bond and including the resultant product as a raw material. The resin composition can be polymerized and solidified by a crosslinking agent and an addition polymerization initiator. The resin composition can also be obtained by compounding decomposed material of the urethane resin with a compound having ≥2 carboxy groups or its anhydride. The regenerated resin having good characteristics can be obtained by carrying out curing reaction of the resultant resin composition.
