Abstract
Oppfinnelsen angår en fremgangsmåte for fremstilling av en modifisert amino-formaldehyd-harpiks, som omfatter: a) et blandetrinn, hvor en væskefase, en amino-formaldehyd-harpiks og fri formaldehyd bringes sammen for å danne en blanding, hvorved amino-formaldehyd-harpiksen har et molart formaldehyd til (NH2)2 forhold (F/(NH2)2 forhold) som ligger mellom 0,5 og 3 og har en vektmidlere molekylvekt som ligger mellom 500 og 50 000, og hvorved det totale molare F/(NH2)2 forholdet i blandingen er høyere enn det molare F/(NH2)2 forholdet av amino-formaldehyd-harpiksen og ligger mellom 2 og 6; b) et F-bindetrinn, hvor blandingen bringes til betingelser hvorved minst en del av den fri formaldehyden reagerer med amino-formaldehyd-harpiksen til å danne en formaldehyd-anriket amino-formaldehyd-harpiks, slik at F/(NH2)2 forholdet av den formaldehyd-anrikede amino-formaldehyd-harpiksen er minst 1 høyere en det av amino-formaldehyd-harpiksen; c) et alkyleringstrinn, hvor en alkohol og en syre med en pKa lavere enn 6 tilsettes til blandingen, blandingen bringes så til betingelser hvorved minst en del av alkoholen reagerer med den formaldehyd-anrikede amino-formaldehyd-harpiksen for å danne den modifiserte amino-formaldehyd-harpiksen, hvorved trinn a) og b) kan utføres enten sekvensielt eller samtidig. Oppfinnelsen angår videre en modifisert amino-formaldehyd-harpiks, som er oppnåelig ved fremgangsmåten, samt anvendelse av harpiksen, spesielt i beleggssammensetninger. ?? ?? ?? ?? 2
