PREPARATION OF POLYACRYLATES BY EMULSION POLYMERIZATION

Preparation of polymers involves emulsion polymerization of monomers in polymerized-in form, (a) 30-70 wt.% of an ester of (meth)acrylic acid with 1-4C alcohol, (b) 30-70 wt.% of (meth)acrylic acid, (c) 0.1-20 wt.% of monomer substituted with at least one 8-30C radical, and (d) 0-20 wt.% of monomers...

Zusammenfassung:	Preparation of polymers involves emulsion polymerization of monomers in polymerized-in form, (a) 30-70 wt.% of an ester of (meth)acrylic acid with 1-4C alcohol, (b) 30-70 wt.% of (meth)acrylic acid, (c) 0.1-20 wt.% of monomer substituted with at least one 8-30C radical, and (d) 0-20 wt.% of monomers different from (a)-(c), with a first polymerization stage and a second polymerization stage, where the weight fractions of the monomers (a)-(d) in the first and second polymerization stages are given in equations as given in the specification.
