Abstract: A surface active agent composition is prepared including: a polymerizable monomer surface active agent and a polymerizable dimer surface active agent represented by the following chemical formula. In the following chemical formula, R1s each are independently an alkyl group having 8 to 30 carbon atoms, R2s each are independently hydrogen or a methyl group, As each are independently an alkylene group having 2 to 4 carbon atoms or a substituted alkylene group, and ns each are independently an integer from 0 to 200. The surface active agent composition is capable of providing for an emulsion exhibiting excellent mechanical stability and polymerization stability, which in turn is capable of forming a film having sufficiently high adhesion and water resistance.

Abstract: There is provided a dispersing emulsion excellent in storage stability and mechanical stability, particularly an asphalt modifier of an water based dispersing emulsion, which can be mixed with a hot asphalt or an asphalt emulsion, and can improve rutting resistance, toughness, and flexibility at a low temperature without losing workability. There is provided a dispersing emulsion of a thermoplastic elastomer, which is emulsified and dispersed in the presence of at least one nonionic emulsifier selected from the group consisting of a styrenated phenol poly(alkylene oxide), a poly(alkylene polyamine) poly(alkylene oxide), polyalcohol fatty acid esters, polyalcohol fatty acid esters poly(alkylene oxide), and a benzylated phenol poly(alkylene oxide).

Abstract: The decomposition reactive emulsifier of this invention is a compound of formula (I): wherein R1 and R2 are the same or different and each represents an alkyl or alkenyl group of from 1 to 20 carbon atoms or a hydrogen atom and both R1 and R2 are not concurrently a hydrogen; R3 is a hydrogen atom or a methyl group; A is an alkylene or substituted alkylene group of 2 to 4 carbon atoms; n is an integer of from 1 to 100 when X is a hydrogen atom or n is an integer of from 0 to 100 when X is an ionic hydrophilic group, said ionic hydrophilic group being anionic, cationic or amphoteric and when n is 2 or greater (AO)n is a homopolymer or a block copolymer or a random copolymer.

Abstract: Sugar or sugar-alcohol fatty acid esters such as sucrose fatty acid esters are synthesized by incubating an aqueous mixture of a sugar or sugar-alcohol, a fatty acid and a catalytically active amount of a lipolytic enzyme, and recovering the resulting ester from the mixture.
