ORGANOCLAY COMPOSITIONS MANUFACTURED WITH ORGANIC ACID DERIVED ESTER QUATERNARY AMMONIUM COMPOUNDS, THEIR PREPARATION AND NON-AQUEOUS FLUID SYSTEMS CONTAINING SUCH COMPOSITIONS

摘要

A novel organophilic clay comprising the reaction product of: (a) a smectite-type clay; and (b) a quaternary ammonium compound or compounds selected from the group consisting of: (see above formula) wherein R1 is an unsaturated alkyl-ester group having 8 to 30 carbon atoms a s described below and R2, R3 and R4 are independently selected from the group consisting of (i ) R1, (ii) long chain linear or branched alkyl (including methyl), aliphatic or aromatic groups having 1 to 30 carbon atoms (such groups can also include hydroxylated groups); (iii) aralkyl groups, which are benzyl and substituted benzyl moieties, including such groups having fused ring moieties having linear chains or branches of 1 to 30 carbon atoms; (iv) aryl groups such as phenyl and substituted phenyl including fused ring aromatic substituents; (v) beta, gamma unsaturat ed groups having six or less carbon atoms or hydroxyalkyl groups having 2 to 6 carbon atoms; and (vi) hydrogen and M- is an anion selected from the group consisting of chloride, methylsulfate , acetate, iodide and bromide. The organophilic clay is used in a non-aqueous fluid system such as paints, inks, and coatings to provide improved rheological properties.
