摘要

Monomer of formula (I): R - (AO) m - (BO) n - R 'where: - myn are integers less than 150 of which at least one is not null, - A and B designate different alkyl groups one of the another, and with 2 to 4 carbon atoms, designating the AO group preferably ethylene oxide and designating the BO group preferably propylene oxide, - R designates a polymerizable unsaturated function, preferably methacrylate, - R 'being characterized in that it is consisting of at least one grouping of formula (II): CH3 - (CH2) p - CH (CH2) rCH3 - (CH2) q - where p and q designate integers of which at least one is not null, with 5 p + q 13, r is an integer equal to 0.
