Abstract: An aqueous spray can coating material comprising at least one water-soluble or water-dispersible copolymer of ethylenically unsaturated monomers, said copolymer being preparable by an at least two-stage free-radical copolymerization, initiated by oil-soluble thermolabile free-radical initiators, in at least one organic solvent, of (A) at least one ethylenically unsaturated monomer containing at least one hydrophilic functional group (a) which renders the copolymer water-soluble or water-dispersible, and (B)at least one ethylenically unsaturated monomer containing no functional group (a), where, in at least one stage, the monomer (A) employed therein or the monomer mixture (A/B) employed therein would per se form a water-soluble or water-dispersible polymer or copolymer, and its use to coat primed and unprimed substrates.

Abstract: Polymers are prepared from olefinically unsaturated monomers in an aqueous medium using a free radical initiator system which is soluble in this medium and consists of an oxidizing agent, a reducing agent and an iron salt, by a process in which a corresponding redox initiator system which contains a vanadium salt is used in addition to this iron-containing redox initiator system, and the content of olefinically unsaturated residual monomers in aqueous polymer mixtures or solutions is reduced by this process.

Abstract: The invention relates to a process for preparing 3-methyl-2-butene-4-olide by the codimerization of methylenecyclopropane with carbon dioxide (CO.sub.2) in the presence of organic complex compounds of transistion metals, which process is characterized in that the codimerization is carried out at a temperature of 100.degree. C. to 200.degree. C. in the presence of palladium(O) compounds which are stable in the reaction mixture up to 200.degree. C. and with CO.sub.2 under a pressure of 10 to 110 bar, optionally in the presence of a solvent.
