Abstract
Rozwiązanie dotyczy sposobu otrzymywania kompozytów poliftalamidów z nanonapełniaczem krzemionkowym w wieloetapowym procesie, przez reakcję diamin z dikarboksylowymi kwasami aromatycznymi lub ich mieszaninami z dikarboksylowymi kwasami alifatycznymi, ?-aminokwasami lub/i ich laktamami i następnie oligomeryzację i polikondensację utworzonych soli, prowadzonym w obecności nanonapełniacza krzemionkowego w środowisku reakcji, przy czym nanonapełniacz krzemionkowy wytwarzany jest metodą zol - żel i wprowadzany do środowiska reakcji w postaci zolu lub nanoproszku lub aglomeratów nanokrzemionki mających postać makrosfer, w ilości 0,1 - 4%wag. w stosunku do poliftalamidu.The solution concerns the method of obtaining polyphthalamide composites with a silica nanofiller in a multistage process, by reacting diamines with dicarboxylic aromatic acids or their mixtures with dicarboxylic aliphatic acids, β-amino acids or / and their lactams, and then oligomerization and polycondensation of formed salts, carried out in the presence of silica reaction medium, whereby the silica nanofiller is produced by the sol-gel method and introduced into the reaction environment in the form of a sol or nanopowder or nanosilica agglomerates having the form of macrospheres, in an amount of 0.1 - 4 wt. relative to poliftalamid.
