An aqueous composition for inhibiting the corrosion of metals placed therein is described. The composition comprises a non-oxidizing acid, and, as a corrosion inhibitor, an effective amount of a 3-dialkylamino-3-phenylethenylprop-1-yne.

Disclosed are improved styrene-butadiene (SBR) core-alkyl acrylate/methacrylate shell-polymer compositions and an improved process for applying patterns to textiles by screen printing employing these polymer compositions as binders. The process for preparing the improved polymers is also set forth. The core comprises an SBR copolymer which contains an antioxidant and is at least partially encased by an integral shell of a copolymer of an alkyl acrylate or methacrylate which is formed by copolymerization with an ultraviolet light stabilizer. When used as binders for screen printing, these compositions produce textiles which exhibit a desirable combination of crock fastness, cyclic aging and hand properties.

An aqueous composition for inhibiting the corrosion of metals is described. The composition comprises a non-oxidizing acid, and, as a corrosion inhibitor, an effective amount of a 3-dialkylamino-3-(1-ethylpentyl)prop-1-yne.

Corrosion inhibitors containing 3-dialkyl-3-(1-ethylpentyl)-prop-1-yne

An aqueous composition for inhibiting the corrosion of metals placed therein is described. The composition comprises a non-oxidizing acid, and, as a corrosion inhibitor, an effective amount of a 3-di(higher)alkylamino-3-phenylprop-1-yne.

Corrosion inhibitors

A corrosion inhibitor for aqueous solutions of mineral acids consisting essentially of the reaction product obtained by the catalytic ethynylation of a dialkylamine, a substituted benzaldehyde and acetylene, said reaction product being a complex material which contains predominately a 3-dialkylamino-3-(substituted phenyl) prop-l-yne.

Acrylic polymer latex thickened with a latex containing a copolymer derived from (1) methacrylic acid or ethacrylic acid, and (2) methylacrylate.

Thickened acrylic polymer latices

Butadiene-styrene latex thickened with an emulsion containing a terpolymer derived from (1) methacrylic acid or ethacrylic acid; (2) a C.sub.1-8 alkylester of acrylic, methacrylic or ethacrylic acid, and; (3) acrylamide or styrene optionally nuclearly substituted by methyl or ethyl.

Disclosed are improved core-shell polymer compositions and an improved process for applying patterns to textiles by screen printing employing these polymer compositions as binders. The polymer comprises a core of styrene-butadiene copolymer which is at least partially encased by an integral shell of a copolymer of butyl methacrylate and methyl acrylate. When used as a binder in a screen printing process, this composition produces textiles which exhibit a surprisingly desirable combination of the properties of crock fastness, cyclic aging and hand.

Terpolymer emulsions comprising (1) an .alpha.,.beta.-unsaturated carboxylic acid (2) an alkyl ester of an .alpha.,.beta.-unsaturated carboxylic acid, and (3) an amide of an .alpha.,.beta.-unsaturated carboxylic acid or styrene or a derivative thereof of the formula ##STR1## in which R.sub.2 is hydrogen, methyl or ethyl are useful as thickening agents, particularly in butadiene-styrene latices.
