Method for producing acrylic polymer, acrylic polymer, and plastisol composition
Disclosed is a method for producing a plastisol acrylic polymer which can have a satisfactory adhesion property even when the heating time is short and the heating temperature is low, and which has excellent storage stability. The method comprises (1) a step of polymerizing an acrylic monomer mixture (a) to produce a polymer (a) and (2) a step of polymerizing an acrylic monomer mixture (b) in a dispersion containing the polymer (a), wherein a monomer having a hydroxy group is contained in the acrylic monomer mixture (a), a monomer having an acetoacetyl group or a block isocyanate group is contained in the acrylic monomer mixture (b), and the dissolution parameter (sa) for the polymer (a) and the dissolution parameter (sb) for a polymer (b) produced by the polymerization of the acrylic monomer mixture (b) are different from each other..

Aqueous dispersions of microgel encapsulated particles utilizing hyperbranched acrylic polymers
An aqueous dispersion includes particles at least partially encapsulated in a microgel where the microgel is prepared from a hyperbranched acrylic polymer. In addition, a method for making an aqueous dispersion includes: (1) mixing in an aqueous medium: (a) particles, (b) at least one ethylenically unsaturated monomer, and (c) a water-dispersible hyperbranched acrylic polymer having ethylenic unsaturation; and (2) polymerizing the at least one ethylenically unsaturated monomer and water-dispersible hyperbranched acrylic polymer having ethylenic unsaturation to at least partially encapsulate the particles in a microgel..
