    Abstract: Provided are a process, the process includes (i) first, contacting a textile with an aqueous solution containing a cationic hydroxyethylcellulose polymer to form a modified textile component; (ii) subsequently, impregnating the modified textile component with an aqueous polyurethane dispersion externally stabilized with an anionic surfactant, the aqueous polyurethane dispersion including a second surfactant; and (iii) precipitating the polyurethane in the modified textile component. Also disclosed are a synthetic leather produced by the process.

    Abstract: A rosin dispersion is a reaction product of, by dry weight based on total dry weight of the rosin dispersion, from 80% to 98% a rosin resin, and from 2% to 20% a dispersant. The rosin resin is processed by at least one method of a) modification, b) hydrogenation or disproportionation, and c) polymerization or esterification from raw material rosins. The dispersant is selected from C18-C32 aliphatic carboxylic acids, olefin (meth) acrylic acid copolymers, and other acid/anhydride modified polymers. A continuous process for preparing the rosin dispersion and an adhesive formulation comprising the rosin dispersion are also included.

    Abstract: Disclosed is an acrylic adhesive composition comprising: A) a polymer polymerized from a monomer mixture comprising (a) 40-90 wt % of C6-C10 alkyl acrylate; (b) 3-15 wt % of methyl (meth)acrylate; (c) 0.1-5 wt % of an ethylenically unsaturated compound having at least one keto or aldehyde group; (d) 0-2 wt % of an ethylenically unsaturated acid; (e) 0-30 wt % of other ethylenically unsaturated monomers; wherein the percentages are based on the total weight of the monomer mixture; and B) a polyhydrazide compound having at least two hydrazide functional groups which react with the keto or aldehyde groups by a crosslinking reaction.
