Abstract: There is provided a tackifier composition especially suited for use with natural rubber latex and formed from an olefin resin, preferably a polymerized terpene hydrocarbon resin condensed with an unsaturated carboxylic acid or anhydride, optionally partially esterified with a C.sub.1 -C.sub.30 alcohol or phenol, and neutralized with a base, preferably a volatile base such as an amine, and then dispersed in an aqueous medium. The tackifier when added to a latex forms compositions useful particularly as pressure sensitive adhesives.

Abstract: There is provided a process for recovery of fatty acids from tall oil heads comprising the steps of neutralizing the acids with a mixture of a magnesium soap forming compound and an alkali metal soap-forming compound under fusion conditions, stripping out unsaponifiables and springing the fatty acids with a mineral acid.

Abstract: There is provided a stabilized aqueous base tackifier composition characterized by the presence in an aqueous medium of a resinous tackifier composition having an acid number in the range from 30 to 150 and a softening point in the range of from -40.degree. to 150.degree. C., a minor amount of a nonionic or anionic surfactant and a minor amount of an elastomeric latex. There is also provided a method of stabilizing an emulsifiable tackifier composition which comprises adding to such composition, a minor amount of a surfactant and a minor amount of an elastomer.

Abstract: Elevated temperature process for deoiling spent crystalline clay from the refining of glyceride esters ("oils") wherein a primary dispersion of such spent clay and aqueous alkali are mixed under pH conditions effective for removing a substantial amount of oily phase from such clay in the form of glyceride esters, thus-treated clay is separated and redispersed with additional aqueous alkali under pH conditions effective for saponifying at least a substantial fraction of the remaining glyceride esters present, then the treated clay is separated from the redispersion.

Abstract: A resinous polyelectrolyte, especially suitable for use as a tackifier in latex adhesives, comprises an ionizable resinous mixture which is ionized with a volatile ionizing agent, said ionizable resinous mixture being the reaction product of a rosin, a carboxylic acid, and a C.sub.1 -C.sub.18 mono-alcohol, said ionizable resinous mixture having a softening point not substantially above about 125.degree. C. and an acid number of between about 30 and 150, said reaction product comprising the carbocyclic nucleus of rosin having at least one carboxylic acid group and at least one carboxylic acid ester group of said mono-alcohol.

Abstract: A flow process for conjugating unconjugated unsaturation of fatty acids in the presence of alkali metal hydroxide under at least autogenic pressure at elevated temperature with control of the cis/trans to trans/trans ratio of the conjugated fatty acid product.

Abstract: Process for treating tall oil heads with alkali at elevated temperature for recovery of heads fatty acids is improved by performing a fusion cook of such heads initiated with essentially dry alkali.

Abstract: Process for washing fatty acids from spent clay, such as spent bleaching clay, with aqueous alkali at elevated temperature is improved by establishing and maintaining the mixture of aqueous phase and fatty acid at a pH between about 5 and about 6.5.
