Modified organophilic clay complexes

Organoclay compositions manufactured with organic acid derived ester quaternary ammonium compounds

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: ##STR1## wherein R 1 is an unsaturated alkyl-ester group having 8 to 30 carbon atoms as described below and R 2 , R 3 and R 4 are independently selected from the group consisting of (i) R 1 , (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 unsaturated 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.

Higher dialkyl dimethyl ammonium clay gelling agents for unsaturated polyester compositions

Known higher dialkyl dimethyl ammonium clays can be surprisingly used as thixotropic agents in reinforced thermoset resins containing a major proportion of an unsaturated polyester and a minor proportion of styrene type monomer by employing a novel pregel process. In this process, the quaternary ammonium clay is pregelled in the styrene and the resulting pregel is then mixed with the unsaturated polyester to produce the final gel which is usually combined with glass fiber as a reinforcing agent for the production of thermoplastics. The novel clay gel compositions of the present invention have surprisingly advantageous properties, compared to the presently used fumed silica gel compositions.

Overtreated higher dialkyl dimethyl ammonium clay gellants and their use in greases

Polyolefin based greases gelled by clays overtreated by higher dialkyl dimethyl ammonium salts

Polyolefin lubricant base oils can be surprisingly gelled by layer and chain type overtreated higher dialkyl dimethyl ammonium clays preferably containing a minimum of 12% excess of the quaternary ion moiety over their ion exchange capacity. For example, an overtreated dihydrogenated ditallow ammonium montmorillonite containing a 22% excess of the quaternary ion can be used to prepare a polydecene based grease although it does not gel mineral oil lubricants. In contrast, the known clay analog of equivalent treatment gels the mineral oil but not the synthetic polyolefin lubricant under comparable conditions.
