Title:
ポリイソブチレンをベースとする親水性乳化剤
Document Type and Number:
Japanese Patent JP2005504150
Kind Code:
A
Abstract:
The invention relates to amphiphilic compounds and mixtures thereof and processes for their preparation and their use in oil-in-water emulsions. The compounds are composed of a lipophilic and a hydrophilic part. The two parts are linked to one another by a linker derived from succinic acid. The lipophilic part is formed by a polyisobutylene group having a number average molecular weight Mn of from 300 to 10 000. The hydrophilic part preferably comprises at least two polyethylene glycol chains which can be prepared by reacting -OH, -N(H)- and/or -NH2 with ethylene oxide. A globular, nonlinear structure of the hydrophilic part is thus obtained, so that the hydrophilic character of the novel compounds predominate and said compounds are particularly suitable for oil-in-water emulsions. The invention additionally relates to formulations for treating metal surfaces, especially for corrosion protection, comprising at least one compound of the invention, at least one solvent capable of dissolving, dispersing, suspending or emulsifying the compound/s of the invention, and, if desired, further components. The process is for treating metal surfaces by contacting them with the formulation of the invention, and also coated metal surfaces themselves, are likewise provided by the present invention.
