摘要： The present invention relates to a waterborne dispersion comprising (A) amphiphilic block copolymer obtained with a controlled radical polymerization process and comprising at least blocks [A] and [B], whereby block [A] comprises ethylenically unsaturated monomer(s) bearing water-soluble and/or water-dispersible functional groups (monomer(s) (i)), and block [B] comprises ethylenically unsaturated monomer(s) different from monomer(s) (i) (monomer(s) (ii)); and (B) polymer P comprising ethylenically unsaturated monomer(s) different from (i) (monomer(s) (ii)), characterized in that the amount of block copolymer is higher than 1 and lower than 30 wt. %, based on the total weight of monomers used to prepare the block copolymer and polymer P; the acid value of the composition consisting of block copolymer and polymer P is higher than 1 and at most 35 mg KOH per g of the block copolymer-polymer P composition; the block copolymer has a calculated glass transition temperature of higher than 10° C. and lower than 250° C.; and polymer P comprises at least 20 wt. % (relative to the total monomer composition to prepare the polymer P) of a polymer fraction with calculated glass transition temperature higher than 10° C. and lower than 100° C.

摘要： The present invention relates to a dispersion comprising (A) a carrier fluid in an amount from 35 to 95 wt. %, the carrier fluid comprising: (A1) water, and (A2) at least one compound selected from the group consisting of ethanol, 1-propanol, 2-propanol, ethyl acetate, n-propyl acetate, isopropyl acetate, acetone, methyl ethyl ketone and any mixture of at least two of these compounds, whereby the amount of water (A1) relative to the carrier fluid (A) is less than 85 wt. % and the amount of water relative to the dispersion is from 1 to 30 wt. %; and (B) polymer(s) in an amount from 5 to 65 wt. %, the polymer(s) comprising: (B1) polymeric particles having a volume average particle size from 1 μm to 20 μm, whereby the polymer of the polymeric particles (B1) has a weight average molecular weight of at least 100 kDaltons and whereby the polymer of the polymeric particles (B1) is selected from the group consisting of polyurethane, polyurethane-polyacrylate hybrid and any mixture thereof; and whereby the amounts of (A) and (B) are given relative to the total amount of (A) and (B).

摘要： The present invention further relates to a waterborne dispersion comprising (A) polymer P; (B) amphiphilic block copolymer obtained with a controlled radical polymerization process and comprising at least blocks [A] and [B], whereby block [A] comprises ethylenically unsaturated monomer(s) bearing water-soluble and/or water-dispersible functional groups (monomer(s) (i)), and block [B] comprises ethylenically unsaturated monomer(s) different from monomer(s) (i) (monomer(s) (ii)); and (C) crosslinker, characterized in that the polymer P is crosslinkable and comprises ethylenically unsaturated monomer(s) bearing crosslinkable functional groups different from monomer(s) (i) and monomer(s) (ii) (monomer(s) (iii)) in an amount of from 1 to 10 wt. %, based on the total weight of monomers used to prepare the polymer P, the amount of lock copolymer is higher than 1 wt. % and lower than 30 wt. %, based on the total weight of monomers used to prepare the block copolymer and polymer P; the acid value of the composition consisting of block copolymer and polymer P is higher than 1 and lower than 17 mg KOH per g of the block copolymer-polymer P composition.
