Abstract
Det beskrives en fremgangsmåte for fremstilling av vann- løselige fosfatestere av guargummi ved å blande guargummien med en vandig løsning av et natriumsalt av fosforsyre med en pH-verdi på ca. 5 til ca. 7, tørke blandingen til et fuktig- hetsinnhold på ca. 5 til ca. 12% og oppvarme blandingen i et lukket kammer ved en temperatur på ca. 150 til ca. 180*C i ca. 1-5 timer.
