Lofted non-woven materials are formed by bonding fibres and used for, e.g. furniture filing and heat insulation. The flammability of these materials is an important characteristic. The use of copolymer emulsions having defined Tg, molecular weight and solution viscosity as binders allows the material to melt away from an open flame. Thus the flammability of the non-woven material is reduced.

Aqueous emulsion adhesives having a pH from 2 to 6 which comprise homo- or copolymeric polyvinyl esters, polymeric protective colloids, water-soluble compounds which can be complexed with the polymeric protective colloids, and at least partially masked polyaldehydes having at least 3 carbon atoms from which aldehyde groups can be released in a controlled manner in acidic media are suitable for bonding porous and semiporous substrates.

The present invention relates to an aqueous emulsion comprising a dispersant of a modified polyvinyl alcohol with an ethylene unit content of 2 to 9 mol % and a degree of hydrolysis of at least 95 mol %, a dispersoid of a polymer of an ethylenically unsaturated monomer, and a ratio (.eta.2 rpm/.eta.20 rpm) of Brookfield viscosity at 30.degree. C., 2 rpm (.eta.2 rpm) as against Brookfield viscosity at 30.degree. C., 20 rpm (.eta.20 rpm) being 1 to 1.8 when the latter viscosity (.eta.20 rpm) is ad...

The present invention relates to oil-in-water emulsion compositions useful for topical application to human skin. These compositions comprise from about 5% to about 60% by weight of the total composition of an oil phase having a viscosity from about 3000 cps to about 10,000,000 cps, wherein the oil phase comprises from about 0.1% to about 10% by weight of the total composition of a particulate thickener for the oil phase, and from 0% to about 10% by weight of the total composition of an oil phas...

An injectable physiologically acceptable aqueous phase fluorocarbon emulsion, which has substantially no free fluorocarbon, has an excellent stability is prepared by a process of the invention. Typically, more than about 99.8 wt. % of the fluorocarbon remains in the size range of about 0.2 to 0.4 microns even after being stored at room temperature for one year or more in sealed containers under a non-oxidizing atmosphere. The emulsion is useful in medical applications, for example, coronary angi...

An antiperspirant liquid composition in the form of an emulsion comprises a volatile polydimethylsiloxane, a wax, an antiperspirant agent, an emulsifier and water. The wax is first dissolved in the polydimethylsiloxane and then emulsified with the remaining ingredients. The composition can be sprayed on the skin yet is thick enough not to form runs or dribbles on the skin under the influence of gravity.

A copolymer emulsion comprising (I) a copolymer obtained by copolymerizing (A) a dicyclopentadiene derivative, (B), an .alpha.,.beta.-unsaturated monomer having one or more OH groups, (C) an .alpha.,.beta.-unsaturated monomer copolymerizable with the components (A) and (B), followed by the reaction of the resulting copolymer with (D) a partial allyl ether of polyhydric alcohol having one or more terminal isocyanate groups, and (II) water can be cross-linked and cured at normal temperatures to gi...

An emulsion of a crosslinking type comprises an oligoester-(meth)acrylate having at least two (meth)acryloyl groups in a molecule, a molecular weight of not more than 1000 per one (meth)acryloyl group, and a boiling point at a normal pressure of at least 200.degree. C and a polymer emulsion of an oil-in-water type.

An emulsion composition prepared by the emulsion polymerization of a polymerizable vinyl monomer in the presence of an emulsifier characterized in that the emusifier is a neutralized maleate, partial maleate, fumarate or partial fumarate of an addition polymerization polymer having as a side chain a drying oil fatty acid residue and/or semi-drying oil fatty acid residue linked to the main chain of the polymer by an ester bond.

An emulsion composition prepared by the emulsion polymerization of a polymerizable vinyl monomer in the presence of an emulsifier characterized in that the emulsifier is a neutralized copolymer of (A) a monomer prepared by being allowed at least one glycidyl ester of arcylic acid and methacrylic acid to react with at least one fatty acid of drying oil fatty acid and semi-drying oil fatty acid, (B) .alpha.,.beta.-ethylenically unsaturated acid and (C) an unsaturated monomer containing substantial...
