METHOD FOR OBTAINING THICKENERS AND APPLICATION OF THICKENING AGENTS OBTAINED IN THIS WAY IN HIGH VISCOSITY COMPOSITIONS CONTAINING UNSATURATED COMPLEX POLYESTER

摘要

The invention relates to the use of at least one mixed mineral organoclay rheology additive, which comprises or consists of a quaternary alkyl-ammonium salt treated mineral clay mixture prepared by forming an aqueous hormite clay slurry (a), forming an aqueous smectite clay slurry (b), combining the aqueous hormite clay slurry (a) with the aqueous smectite clay slurry (b) to form a combined clay slurry (c), treating the combined clay slurry (c) with one or more quaternary alkyl-ammonium salts, and separating the thus produced quaternary alkyl-ammonium salt treated mineral clay mixture from the aqueous medium. The invention also relates to a process for producing a mixed mineral organoclay rheology additive and the use of the thus produced additive as a thickening agent in liquid compositions.
