Abstract: The present invention relates to a process for purifying benzenepolycarboxylic esters and for preparing cyclohexanepolycarboxylic esters by hydrogenating the purified benzenepolycarboxylic esters. The invention further relates to benzenepolycarboxylic esters and cyclohexanepolycarboxylic esters having a small proportion of by-products, especially of dialkyl ethers, and especially to diisononyl cyclohexane-1,2-dicarboxylate having a small proportion of diisononyl ether. The invention also relates to the use of the cyclohexanepolycarboxylic esters as plasticizers, especially in products intended for human contact, such as children's toys, food packaging and medical articles.

Abstract: A process for the distillation of a mixture which consists to at least 90% by weight of a cyclic N-vinylamide and which comprises a stabilizer, wherein a polyether is added to the mixture before or during distillation and a product is obtained which consists to at least 99.5% by weight of the cyclic N-vinylamide.

Abstract: The present invention relates to electrodeposition primer compositions comprising catalytically active core/shell particles CS. The electrodeposition primer compositions can be used more particularly for cathodic dip coating for the coating of automobile bodies or parts thereof.

Abstract: The present invention relates to a dispersion comprising (i) at least one liquid polymer and (ii) at least one polymer particle mixture comprising at least one meltable solid and at least one copolymer (C), wherein said at least one copolymer (C) is a random copolymer synthesized from at least one ?,?-ethylenically unsaturated monomer and at least one polymerizable polymer of the class of liquid polymers according to (i), to processes for preparing this dispersion, to the use of this dispersion to prepare polyurethanes, and to a process for preparing polyurethanes, in which at least one such dispersion is reacted with at least one polyisocyanate.
