The polymer which possesses the functional group by the amino acid or amino acid derivative, the synthesis method, and use the surface active agent in the constituent for make-up, especially, as a manicure

摘要

(57) Abstract This invention relates to the polymer which possesses, the chain terminal functional group of the below-mentioned formula, in formula, the - polymerization chain (P), it is the hydrophobic chain which can at least by the radical polymerization reaction of a kind of monomer, R, the hydrogen atom, or, has 8 carbon atoms from 1, direct or it is the branching chain hydrocarbon chain, is optional, but CO₂ H and NH₂, OH or, to be something at least displacement with one which is chosen from the phenyl group which the basic very thing is displacement optionally basis, as for A and B, being identical,Even with the material which differs it is good, single bond, direct or the hydrocarbon chain of the branching chain is displayed respectively with saturation or the unsaturated it consists of 16 carbon atoms from 1, but in addition, amide join, or, 4 amino acids, especially, the fact that the peptide chain which possesses natural amino acid is included possible from 2, the nh2 and/or COOH basis has been allowed to have separated and, it is possible to form the salt. This invention furthermore furthermore specific as a surface active agent of the above-mentioned product, it relates to the use which is used as a penetrant, as a dispersant of the solid-state grain, the micro dispersing element of the polymer, especially, as one for preparation of the micro gel and the micro latex.
