Abstract

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.

First claim

The invention claimed is:

1. A method for producing an acrylic polymer, the method comprising:
polymerizing an acrylic monomer mixture (a) to obtain a polymer (A);
and polymerizing, an acrylic monomer mixture (b) in a dispersion comprising, the polymer (A),
wherein
the acrylic monomer mixture (a) comprises a monomer having a hydroxyl group,
the acrylic monomer mixture (b) comprises a monomer having an acetoacetyl group or a blocked isocyanate group, and
a solubility para…
