Abstract
This invention relates to compositions which are the reaction products of phenol-formaldehyde resins, .alpha.-olefin epoxides derived from .alpha.-olefins of 4 or more carbons and alkylene oxides such as ethylene and propylene oxides; and to the use of these compositions as dehazers for petroleum distillates.
Claims25
The process which comprises reacting a phenolformaldehyde resin with an .alpha.-olefin epoxide having at least four carbon atoms and then reacting the product so obtained with a member of the group consisting of ethylene oxide, glycidol, propylene oxide and mixtures thereof, the reaction of said phenol-formaldehyde resin with said .alpha.-olefin epoxide and the reaction of the product so obtained with said member being carried out by heating the respective reaction mixtures.
