Examples
Embodiment 1
[0024] Add 50 moles of polytetrahydrofuran glycol (PTMG) with a molecular weight of 500 into a reaction kettle equipped with a stirrer, a thermometer, a vacuum system and an electric heating mantle, raise the temperature to 105°C, and dehydrate for 2 hours under high vacuum until the water content is low 0.05%, then cooled to 60°C, released the vacuum, added 100 moles of diphenylmethane diisocyanate (MDI), and kept the temperature at 80°C for 2 hours. After defoaming, the prepolymer is obtained. Use 50 moles of 3,3'-dichloro-4,4'diaminodiphenylmethane (MOCA) to carry out chain extension reaction with the prepolymer, and then choose the solution dry method to carry out the spinning forming process.
Embodiment 2
[0026] Add 62 moles of polytetrahydrofuran glycol (PTMG) with a molecular weight of 1000 into a reaction kettle equipped with a stirrer, a thermometer, a vacuum system and an electric heating mantle, raise the temperature to 105°C, and dehydrate for 2 hours under high vacuum until the water content is low 0.05%, then cooled to 60°C, released the vacuum, added 124 moles of diphenylmethane diisocyanate (MDI), and kept the temperature at 80°C for 2 hours. After defoaming, the prepolymer is obtained. Use 62 moles of chain extender 3,3′-dichloro-4,4′diaminodiphenylmethane (MOCA) to carry out chain extension reaction with prepolymer, and then choose solution dry method for spinning forming processing.
Embodiment 3
[0028] Add 71 moles of polytetrahydrofuran glycol (PTMG) with a molecular weight of 2000 into a reaction kettle equipped with a stirrer, a thermometer, a vacuum system and an electric heating mantle, raise the temperature to 105°C, and dehydrate for 2 hours under high vacuum until the water content is low 0.05%, then cooled to 60°C, released the vacuum, added 142 moles of diphenylmethane diisocyanate (MDI), and kept the temperature at 80°C for 2 hours. After defoaming, the prepolymer is obtained. Use 71 moles of chain extender 3,3′-dichloro-4,4′diaminodiphenylmethane (MOCA) to carry out chain extension reaction with prepolymer, and then choose solution dry method to carry out spinning forming process.
