| titleOfInvention | A method of preparing the polyurethane material that side chain contains amino |
| abstract | The invention discloses a kind of methods preparing the polyurethane material that side chain contains amino, include the following steps：(1) synthesis of side chain polyurethane containing alkynyl：By diisocyanate, chain extender small molecule, soft segment macromolecular diol synthesizes side chain polyurethane containing alkynyl under the effect of the catalyst；The chain extender small molecule glycol includes the small molecule glycol containing alkynyl；Wherein, soft segment macromolecular diol and chain extender small molecule total amount and diisocyanate molar ratio are 0.5~2；Small molecule glycol containing alkynyl is 0.05~2 with diisocyanate molar ratio；(2) polyurethane dissolving of the side chain for obtaining step (1) containing alkynyl in a solvent, weighs nitrine amine, cuprous catalysis agent is then added under nitrogen protection, 15~36h is reacted at 10 60 DEG C.The method for preparing the polyurethane material that side chain contains amino of the present invention is efficiently controllable and applied widely. |
