ABSTRACT:
A process for the suspension polymerization of ethylenically unsaturated monomers -- particularly for the preparation of water-soluble polymers -- wherein a liquid monomer phase is polymerized while suspended in a liquid organic suspending medium in the presence of a macromolecular stabilizing or suspending agent having a macromolecular portion or portions solvated by the liquid monomer phase and another macromolecular portion or portions solvated by the liquid organic suspending medium.
Water-soluble suspension polymers, preparable by this process, comprising quaternization products or salts of dialkylaminoalkyl esters or of dialkylaminoalkyl amides of acrylic acid or of methacrylic acid.
