| titleOfInvention | Process for preparation of polyamide from dinitrile and diamine |
| abstract | A two-step process for the production of polyamides from Α, ω-dinitriles and Α, ω-diamines involving the catalytic hydrolysis of the Α, ω-dinitrile by addition of water with simultaneous purging of the reactor (i.e., venting of ammonia and water vapor) in the first step followed by polymerization by addition of the Α, ω-diamine to the hydrolysate in the second step. Such a process is particularly useful in the production of poly(hexamethylene adipamide), i.e., nylon 6,6 from adiponitrile and hexamethylene diamine using lower catalyst levels during hydrolysis and resulting in reduced levels of bis(hexamethylene)triamine, BHMT, in the polymer. |
