Abstract

Tørt, fast, vannløselig, amorft, kationisk po/yamid-epiklor- hydrin-harpikspulver hvor polyamid- delen i harpiksen utgjøres av det langkjedede omsetningsprodukt fra omsetningen av et polyalkylenpolyamid som har to priinære amingrupper og minst en sekundær amingruppe, med en i forbindelse valgt blant C3_8 mettede alifatiske dikarboksylsyrer og lavere alkylestere av C3.B mettede alifatiske dikarboksylsyrer. Harpiksen frem- stilles ved omsetning av det nevnte polyamid med epiklorhydrin i en van- dig løsning, i hvilken molforholdet mellom epiklorhydrin og polyamidets sekundære amingrupper er fra 0,5:1 til 1,8:1. Harpikspulveret fremstil- les ved frysetørking av en vandig løsning av harpiksen.
