| titleOfInvention | It is continuous prepare polyamide oligomer and prepare can thermoplastic processing hypocrystalline or amorphous polyamides method |
| abstract | The present invention relates to a kind of methods for continuously preparing polyamide oligomer.This method includes to be delivered continuously to the aqueous solution of polyamide formation monomer in oligomerization reactor from storage container, the aqueous solution is heated to above solution temperature or storage temperature, wherein limitation residence time of the monomer solution in oligomerization reactor and adjust the vapor partial pressure of pressure or water, so that the conversion ratio that monomer is transformed into polyamide oligomer is no more than maximum value and/or is formed by polyamide oligomer and will not be separated in solid form or spontaneous crystallization, and polyamide oligomer is continuously discharged from oligomerization reactor.Can by be used to prepare hypocrystalline or it is unbodied can the method for polyamide of thermoplastic processing the polyamide oligomer that can be prepared by the method is continuously provided in the mixture with water, then carried out retraction synthesizing polyamides.By means of injection moulding, multicomponent injection moulding, injection moulding welding, extrusion, coextrusion, blowing and deep-draw molded part can be prepared using the polyamide. |
