Abstract
Przedmiotem zgłoszenia jest sposób otrzymywania poliftalamidów przez reakcję diamin z dikarboksylowymi kwasami aromatycznymi lub ich mieszaninami z dikarboksylowymi kwasami alifatycznymi, ?-aminokwasami i/lub ich laktamami, oligomeryzację otrzymanych soli a następnie kondensację oligomerów do końcowego polimeru. Sposób ten polega na prowadzeniu procesu otrzymywania soli z zastosowaniu nadmiaru diaminy, a proces oligomeryzacji prowadzony jest w kilku etapach, gdzie dla każdego etapu dobrane są specyficzne parametry procesu, a niektóre etapy prowadzone są z częściowym usuwaniem wody ze środowiska reakcji co pozwala na uzyskanie, reaktywnych oligomerów, które kondensowane są do produktu końcowego poliftalamidu.The subject of the application is a method for obtaining polyphthalamides by reaction of diamines with dicarboxylic aromatic acids or their mixtures with dicarboxylic aliphatic acids, β-amino acids and / or their lactams, oligomerization of the obtained salts and subsequent condensation of oligomers to the final polymer. This method involves conducting the process of obtaining salts using an excess of diamine, and the oligomerization process is carried out in several stages, where for each stage specific process parameters are selected, and some stages are carried out with partial removal of water from the reaction environment, which allows obtaining reactive oligomers that are condensed into the final product of poliftalamide.
