  • Publication number: 20220372176
    Abstract: The present invention relates to a process for preparing a dispersion (D°), comprising: (E1) a polymerization performed M in an aqueous medium in the presence of: ° at least a pre-polymer (pO) of formula (R11)X—Z11—C(?S)—Z12-[A]-R12, which is soluble in the aqueous medium ° at least one free-radical polymerization initiator; and ° at least one ethylenically unsaturated hydrophobic monomer (m) with a ratio m/pO of the mass of the monomers (m) to the quantity of pre-polymer (pO) preferably below 10 000 g/mol whereby a dispersion of copolymers is obtained, including polymers with a living character; (E2) a conversion of the terminal groups of the copolymers that deprive the copolymers of their living character. The invention also relates to the use of dispersion (D°) for forming dispersions of hydrophobic polymers (Dp), suitable e.g. in fabric conditioning compositions.
