Abstract
An organoclay functional as a rheological modifier for control of the viscosity and thixotropy of polyester-styrene compositions is prepared by a dry process wherein a quaternary ammonium salt is reacted with unfractionated smectite in an aqueous dispersion thereby eliminating the fractionating step required in the typical prior art wet process as exemplified by U.S. Pat. No. 4,240,951 and permitting the preparation of the organoclay rheological modifier to be carried out at a high solids content thereby reducing drying costs in the recovery of the product organoclay.
