Abstract

Foreliggende oppfinnelse tilveiebringer miljøvennlige demulgatorer for å bryte ned petroleumsolje applikasjoner. Demulgeringsformuleringene i henhold til foreliggende oppfinnelse er biologisk nedbrytbare og har lav toksisitet. Demulgatorene innbefatter en poly(tetrametylen glykol) og en alkylen glykol kopolymer forbundet med polytetrametylen glykolen av et difimksjonelt koblingsmiddel.
