The invention relates to a process for the production of foamable copolymers, to foamable copolymers and to foamable polymer structures based on itaconic acid, mesaconic acid, fumaric acid, maleic acid, aconitic acid, and glutaconic acid.
An improved process is disclosed for preparing a hydantoin derivative from a hydrophobic aldehyde or ketone. In the process for preparing a hydantoin derivative by reaction of a hydrophobic aldehyde or ketone with ammonium, cyanide and carbonate ions in water, the reaction is carried out with said hydrophobic aldehyde or ketone emulsified in the presence of a surface-active agent or by vigorous mechanical agitation, whereby the corresponding hydantoin derivative is produced in excellent yields.
