Abstract
A dispersion of reactive polymer particles obtained by polymerization of monomer in an organic liquid which dissolves the monomer but does not dissolve a polymer formed from the monomer, in the presence of a dispersion stabilizer composed of a high molecular weight polymer; characterized in that (i) said dispersion stabilizer is a high molecular weight polymer which is obtained by polymerization of an ethylenically unsaturated monomer and soluble in the above organic liquid and which contains a chemically reactive group (A); that (ii) said polymer particles are particles of a high molecular weight polymer which are obtained by polymerization of an ethylenically unsaturated monomer and contain a complementary chemically reactive group (B) capable of mutually reacting with the chemically reactive group (A); and that (iii) the chemically reactive group (A) and the chemically reactive group (B) are present stably in the dispersion. This dispersion is useful in coating compositions such as an adhesive, coating, etc.
