Continuous process for the production of polyamides |
| abstract |
In a two-step precondensation process for producing a polyamide, a diamine is reacted with a dicarboxylic acid dihalide in a polar, non-basic inert organic liquid medium under conditions such that a condensation product with a low degree of polymerization is formed. The resulting condensate is contacted with an aqueous solution of a water-soluble acid acceptor by continuously feeding the components to a reactor system having a total residence time of about 2 seconds to about 2 minutes and a Peclet number greater than about 3.5. To form a polyamide product having a high degree of polymerization. |
