If (I) contains 1-4C alkyl (meth)acrylate, the amt. of this is max. 30%. Pref. (IA) contains 20-80% (II), 80-20% (III) and 0-30% 1-8C alkyl or 2-3C hydroxyalkyl acrylate, vinyl-acetate, or -propionate and/or acrylamide. (IB) contains 30-60% (II) and 70-40% acrylamide. The inks and pastes contain 0.1-30% (I); (0.5-20% (I)) in inks and 1.5-30% (I) in pastes.

Abstract: Low-molecular-weight polymers of acrylic acid esters are obtainable by subjecting a) from 80 to 100 % by weight of at least one acrylic acid ester of a C1- to C8-alkanol (monomers I) and b) from 0 to 20 % by weight of other copolymerisable monomers (monomers II) to free-radical polymerisation in a pressure vessel at temperatures of from 130 to 140 DEG C in isopropanol solution in such a manner that from 70 to 95 % by weight of a solvent is introduced into the vessel and the remainder of the polymerisation batch is fed in continuously over the course of from 3 to 7 hours in separate feeds, of which one contains the monomers, and, when the polymerisation is complete, the solvent is removed by vacuum distillation, the proportion by weight of the solvent, based on the monomers, being from 5 to 15 %, the proportion by weight of the initiators, based on the monomers, being from 0.5 to 3 %, and the half life period of the initiators at the polymerisation temperature being from 10 seconds to 3 hours. These low-molecular-weight polymers are suitable as external plasticisers in coating compositions based on synthetic resins.

Abstract: Water-soluble terpolymers which contain, as copolymerized units, (a) from 10 to 35% by weight of an N-vinyllactam or an N-vinyl acid amide, (b) from 5 to 20% by weight of acrylic acid or of a salt of acrylic acid and (c) from 80 to 50% by weight of a C1-C4-alkyl vinyl ether, and have a glass transition temperature Tg below 60 DEG C. can be prepared by polymerizing the monomer mixture in an inert organic solvent in the presence of a polymerization initiator and can, where appropriate, be partially or completely neutralized with a base, so as to form a salt. The products may be used as raw materials for adhesives or, in the form of an aqueous solution, as the adhesive itself.
