摘要 |
<p>The invention relates to a multiblock ionomeric copolymer, characterized in that it comprises, for 100 mol %: a) 90 to 99.9 mol % of hydrophobic monomer units (A) from the compound of formula (I): where R1 is a straight or branched alkyl radical comprising 12 to 22 carbon atoms and R2 is a hydrogen atom or a methyl radical; and either b) 0.1 to 10 mol % of monomer units (B) from 2-methyl 2-[(1-oxo 2-propenyl) amino] 1-propanesulfonic acid (also called 2- acrylamido 2-methyl propanesulfonic acid), partially or totally esterified, or c) 0.1 to 10 mol % of monomer units (C) from a cationic monomer, or d) 0.1 to 10 mol % of said monomer units (B) and said monomer units (C). The invention further relates to a method for preparing same and to the use thereof as modifiers of the rheological properties of the oil phase of a topical cosmetic, dermopharmaceutical or pharmaceutical composition.</p> |
