Abstract:
A composition for imparting stain resistance to polyamide substrates comprising a sulfonated fatty composition and sulfonated hydroxyaromatic formaldehyde condensation polymer. A method for making the stain treatment composition, a method for treating polyamide substrates with the composition, and the resulting stain resistance polyamide materials are also disclosed. Suitable sulfonated hydroxyaromatic formaldehyde condensation polymers include sulfonated phenol formaldehyde condensation polymer and sulfonated dihydroxy diphenyl formaldehyde condensate polymer. Suitable sulfonated fatty compositions include sulfonated oleic acid and marine oil.
Abstract:
A curable elastomer composition comprising an elastomer, an unsaturated carboxylic metal salt such as zinc diacrylate, an organic peroxide curing agent such as a ditertiary alkyl peroxide, and phenothiazine as a precure inhibitor. Suitable elastomers include nitrile rubber, EPDM, and EVA. The nitrile rubber is desirably hydrogenated. A method for curing the curable elastomer composition and the resulting cured elastomer compositions are encompassed.
