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. 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 M represents a cation; wherein A'O represents an oxyalkylene group having 3 to 18 carbon atoms, E&#x2032;O represents an oxyethylene group, m denotes a number of 0 to 50 and n denotes a number of 5 to 200, provided that the -(A&#x2032;O)&#x2014; groups m in number [-(A&#x2032;O)m-] may be the same as or different from one another.

Surfactant for emulsion polymerization

According to the present invention, a bulky sheet can be obtained without reducing the effect of a sizing agent. Thus, an ester compound having the melting point of not more than 100&deg; C. selected from (A) an ester compound of a polyhydric alcohol and a fatty acid and (B) an ester compound of a polyhydric alcohol and a fatty acid further including from more than 0 mole to less than 12 moles on the average of C oxyalkylene groups per 1 mole of the said ester compound is used as a paper bulking promoter.

Surfactant composition for emulsion polymerization

Ethoxylate and propoxylated higher alcohol surfactant in high

Surfactant composition

A new melt viscosity depressant for a polyester resin having a structure of an aromatic carbonyl compound is disclosed. Addition of the melt viscosity depressant to a polyester resin reduces the melt viscosity of the resin remarkably, thereby facilitating mold processing and melt-spinning of the polyester resin composition, from which high strength polyester molding products and polyester fibers can be obtained.

Melt viscosity depressant for polyester resin and polyester resin

A cationic dye-dyeable polyester resin composition comprising a cationic dye-dyeable polyester resin and a melt viscosity depressant. Addition of the melt viscosity depressant to the cationic dye-dyeable polyester resin reduces the melt viscosity of the resin without decreasing the intrinsic viscosity thereby making the resin melt-spinnable. A cationic dye-dyeable polyester fiber with high strength can be obtained from the polyester resin composition.

Polyester fibers and process of making

A novel monophosphate and a novel diphosphate prepared by a phosphatidyl transfer reaction of a phospholipid and an alcohol in the presence of phospholipase D are disclosed. The phosphates can independently or together form small and stable liposomes which can include active components therein. Cosmetic compositions comprising these phosphates or liposomes penetrate well into the hair and the skin, and exhibit long-lasting excellent moisture-retaining, beauty, skin-activation effects.

Phosphate, liposome comprising the phosphate as membrane constituent,

A cheese of fiber can be effectively sized with an aqueous emulsion of a cationic polymer, containing 0.2 to 20 g/l of a water-soluble salt, at 30.degree. to 80.degree. C. The polymer preferably includes a copolymer of a vinyl monomer and an unsaturated carboxylic acid on a cationic polymer.
