Foamed microbeads and a process for their preparation

Foamed microbeads with a shell and an encased core are characterized in that the shell is a reaction product of an NCO-containing carbodiimide and a polyamine, and the core is at least partly filled with a polymeric carbodiimide or its reaction product with a polyamine, and in that the foamed microb...

More Information
Summary:Foamed microbeads with a shell and an encased core are characterized in that the shell is a reaction product of an NCO-containing carbodiimide and a polyamine, and the core is at least partly filled with a polymeric carbodiimide or its reaction product with a polyamine, and in that the foamed microbeads are self-supporting and can be laden with hydrophilic and if appropriate hydrophobic liquids.
