The invention provides a surfactant for emulsion polymerization represented by the formula (I), (II) or (VI). The invention also provides a method of producing a polymer emulsion using this surfactant. ##STR00001## wherein A represents an alkylene group having 3 to 18 carbon atoms or an alkoxymethylethylene group (alkoxy group has 4 to 18 carbon atoms), EO represents an oxyethylene group, a denotes a number of 0 to 50, b denotes a number of 0 to 200 wherein a and b are not 0 at the same time and...

Parenteral compositions of oil-coated-Amphotericin B in structured-emulsion form, having LD50 of at least 400 mg/kg in mice and process for making the same have been described. The process essentially requires dispersing Amphotericin B in oily vehicle and dispersing emulsifier in the aqueous phase. The process of present invention is simple, cost effective and gives a stable product suitable for parenteral administration. Amphotericin B emulsion compositions prepared by the process of the presen...

The invention relates to a method of preparing stable oil in water emulsions wherein a ferulyolated compound is at least partly oxidized during or after formation of the oil in water emulsion.

The use of perfluorinated polymers and/or fluorinated ionomers as surfactant emulsifiers in emulsion polymerization of fluorinated monomers.

A method has been disclosed of preparing ultrafine hydrophobic latex particles of polymers and copolymers by free radical emulsion polymerization in a water-based system, making use therefor, in order to polymerize or copolymerize monomers or monomer mixtures respectively, of at least one compound selected from the group consisting of dimers and cobalt complexes, acting as a chain transfer agent (CTA), wherein said latex particles have an average particle size of less than 100 nm, being more tha...

An aqueous polyurethane emulsion having improved wet strength properties in film form, said aqueous emulsion comprising a blend of an aqueous emulsion comprising an internally emulsified ionic polyurethane polymer with a minor amount of an aqueous emulsion comprising epoxy resin.

This invention discloses an emulsion styrene-butadiene rubber (SBR) that can be employed in manufacturing tire tread formulations that have rolling resistance and treadwear characteristics that are similar to those made with solution SBR but with improved traction characteristics. Thus, the emulsion SBR of this invention is superior in many respects for use in tire tread compounds to conventional solution SBR and conventional emulsion SBR. This invention more specifically discloses a styrene-but...

The invention relates to a food product comprising 0.1 to 1.5 wt % of one or more anti-spattering agents comprising no native soy lecithin or native soy lecithin in an amount of from 0 to 0.05 wt % on total product, whereby the anti-spattering agent is preferably selected from the group comprising hydrolyzed lecithin, fractionated lecithin, citric acid esters or combinations thereof; optionally one or more emulsifiers in a total amount of from 0 to 0.5 wt %; optionally one or more browning agent...

The present invention provides an emulsion for pressure-sensitive adhesive, and a pressure-sensitive adhesive product which exhibits high water resistance and high adhesion properties. The emulsion for pressure-sensitive adhesive includes as essential components: a pressure-sensitive adhesive polymer (A) having a glass-transition temperature of -80 to -20.degree. C., a weight-average molecular weight of 150,000 or larger, and a carboxylic acid value of 30 or smaller; a rosin derivative (B) havin...

An emulsion and affluent process which treats and breaks very tight emulsions and separates dissolved solids from associated fluids produced in industry, whereby solids and fluids are separated into clean interfacial phases thus providing an improved quality saleable product resulting in significant reductions in base sediments and water, and compliance with international saleable product and environmental effluent standards with a specific focus on biological oxygen demand and chemical oxygen d...
