Abstract: In the production of vinyl-lactam copolymers by free radical polymerization of water-soluble N-vinyl-lactam(s) and hydrophobic comonomer(s) in an organic solvent in the presence of an initiator, polymerization is carried out under a superpressure high enough to prevent vaporization of the components.

Abstract: In the production of vinyl-lactam copolymers by free radical polymerization of water-soluble N-vinyl-lactam(s) and hydrophobic comonomer(s) in an organic solvent in the presence of an initiator under reflux conditions, the condensate formed in the reflux is recycled into the polymerization mixture from below.

Abstract: Free-radical polymerization of at least one of water-soluble N-vinyl lactam and at least one of hydrophobic comonomer, is carried out in an organic solvent, in presence of initiator under reflux conditions, such that at least 10 mol% of N-vinyl lactam is added to polymerization mixture after at least 90 mol% of hydrophobic monomer is completely reacted. Thus, a vinyl lactam copolymer is produced.

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.
