Abstract

Homopolysakkarid og en oppløsning derav som er oppnådd ved å gå ut fra en blanding på basis av en første homopolymer som er behandlet termisk etter at dens pH er justert til en verdi som er større enn 9.Oppfinnelsen vedrører også en fremgangsmåte for fremstilling av nevntehomopolysakkarid og oppløsning, samt deres anvendelse innen området som vedrører assistert gjenvinning av petroleum.The invention also relates to a process for the preparation of said homopolysaccharide and a solution thereof obtained by starting from a mixture based on a first homopolymer which is thermally treated after its pH has been adjusted to a value greater than 9. solution, as well as their use in the field of assisted petroleum recovery.
