摘要:
The invention relates to a composition in the form of a positive latex comprising a) between 50 wt. % and 80 wt. % of at least one cross-linked, branched, or linear organic polymer (P), b) between 5 wt. % and 10 wt. % of a water-in-oil (W/O) emulsifying system (S1), c) between 5 wt. % and 45 wt. % of at least one oil, and d) between 0 wt. % and 5 wt. % of water. The inventive composition is characterized in that between 0.01 mol. % and 10 mol. % of the monomeric patterns of said monomer P comprise at least one neutral monomer of formula (I): C(R1)(R3)═C(R2)—C(=0)-0-(CH2—CH2—O)n—R4 (I) wherein the radicals R1, R2 and R3, which are the same or different, independently represent a hydrogen atom or a linear or branched alkyl radical comprising between 1 and 4 carbon atoms, the radical R4 represents a linear or branched, saturated or unsaturated, aliphatic radical comprising between 6 and 30 carbon atoms, and n represents a number between 1 and 50. The invention also relates to a method for the production of said composition and the use of the same.
