| titleOfInvention | A kind of preparation method for the double-response water gel for having both soda acid sensitive group |
| abstract | The invention discloses a kind of preparation methods for the double-response water gel for having both soda acid sensitive group.The invention mainly comprises：(1) polyethylene glycol, aliphatic isocyanates, solvent are reacted in a kettle, obtains polyurethane prepolymer；(2) aliphatic isocyanates, the chain extender with acidic-group, solvent are added in a kettle again, the reaction was continued, obtains performed polymer I；The reaction of step (1), (2) is repeated in another reaction kettle, the chain extender with acidic-group is changed to the chain extender with basic group, obtains performed polymer II；Performed polymer I and performed polymer II are poured into same reaction kettle, and add in the crosslinking agent of hydroxyl, solvent, the reaction was continued, obtains polyurethane solutions；Polyurethane solutions are entered into mould, vacuum drying, is impregnated, and add in aziridine crosslinker in alkaline aqueous solution, is reacted, obtain polyurethane hydrogel；Polyurethane hydrogel is impregnated in deionized water, freeze-drying is to get product after immersion. |
