METHOD OF PREPARING GELLED POLYMERIC MICROPARTICLES, PRODUCT PRODUCED THEREBY, AND COMPOSITIONS CONTAINING THE SAME |
| 摘要 |
<p>Crosslinked acrylic polymer microparticles having a particle size of from 0.1 to 10 microns are produced in relatively high concentrations by a method comprising the free radical addition copolymerization of at least one ethylenically-unsaturated monomer with an alpha, beta-ethylenically unsaturated monocarboxylic acid and a crosslinking monomer selected from the group consisting of epoxy group-containing compounds, or a mixture of alklenimine and organoalkoxysilane in the presence of a dispersion stabilizer and a dispersing liquid in which the cross-linked polymer particles are insoluble. These crosslinked polymeric microparticles can be blended with various resins to produce compositions having improved application characteristics as well as other desirable properties.</p> |
