Popis:	A preliminary study was performed on the resinification behavior of regenerated feather keratin powder by changing the sintering conditions, and the thermal and mechanical properties for the obtained resin were investigated. It was confirmed that the molding at 140°C was enough to complete the resinification. The resin obtained was amorphous and its glass transition temperature could be raised to 93°C. In addition, the hardness of the resin could be increased from 20–25 HV to 90 HV by leaving the as-sintered compact resin in ambient air at room temperature for 133 days. Crosslinking agents that work even at room temperature seem to be synthesized during the molding.
