| titleOfInvention | Degradable polyurethane and preparation method thereof |
| abstract | The invention belongs to the field of high polymer materials. The invention relates to degradable polyurethane and a preparation method thereof, wherein the degradable polyurethane is prepared by taking glycerol cyclic carbonate (A), 11-mercaptoundecanoic acid (B), vegetable oil, diamine (C), glycidyl methacrylate (D) and 5-chloro-2-methyl-4-isothiazoline-3-ketone derivative (E) as raw materials through multi-step reaction. The novel vegetable oil-based photocuring polyurethane not only effectively solves the problems of low cyclic carbonate reaction activity and the like in the synthesis process of using toxic isocyanate or vegetable oil-based non-isocyanate polyurethane in the existing vegetable oil-based polyurethane synthesis process, but also has efficient physical properties and antibacterial and bactericidal functions. In addition, the target product contains a large amount of hydroxyl and tertiary amino, and has certain application in the fields of polyester, epoxy curing agent and the like. It is expected that the material will meet wide market prospects, especially in the field of coatings. |
