摘要:
The invention relates to an exhaustion agent, which is an aqueous emulsion of polymerized monomers, wherein the monomers contain: (meth)acrylic acid (MAA); alkyl (meth)acrylate, such as methyl (meth)acrylate (MMA); and a substituted or unsubstituted styrene; and having an average particle size of the emulsified particles is less than about 220 nm.

Permanently soil resistant polymeric compositions that have fluorochemical dispersed throughout the polymer are prepared by melt extrusion of the fluorochemical with the desired polymer. Preferred polymers for extrusion with the fluorochemical are polyester, polypropylene, polyethylene, and polyamide.

摘要:
In situ solvent free methods for making anhydride based graft copolymers which involve mixing an ethylenically unsaturated monomer, an anhydride monomer, either a monofunctional polyglycol having a hydroxyl or amine terminal group or a polyfunctional polyglycol having a weight average molecular weight of greater than 5,000 and at least one terminal hydroxyl group, and a free radical initiator to form a mixture. The mixture is heated to form a copolymer having repeat units derived from the ethylenically unsaturated monomer and anhydride monomer, and a copolymer grafted polyglycol comprising a main polyglycol backbone having copolymer side chains which are heated to form an anhydride based graft copolymer. The anhydride based graft copolymers are especially useful as soil release agents in detergent formulations.
摘要:
A stain resistant composition for fibers having polyamide linkages prepared by polymerizing an α-substituted acrylic acid or ester in the presence of a sulfonated aromatic formaldehyde condensation polymer, or by polymerization of a sulfonated hydroxyaromatic ester of an α-substituted acrylic acid or acrylic acid, and methods for making and applying the composition.
