摘要:
The present invention relates to polyalkylene imine based polymers, which have aliphatic polyester groups attached to the polyalkylenimine backbone via an carboxamide group. The novel polymers are particularly useful as dispersants for pigments, in particular as dispersants for pigments in non-aqueous compositions. The polyalkylene imine based polymers are characterized by having a) a polyalkylene imine backbone; b) at least one aromatic moiety P.1, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide or carboximide group; and c) at least one aliphatic polyester moiety P.2, which is bound to a nitrogen atom of the polyalkylene imine backbone via an carboxamide group.
摘要:
The invention relates to a process for preparing oligo- or polyalkylene ether-modified polysiloxanes by transesterification of alkoxy-functionalized polysiloxanes with OH-terminated oligo- or polyalkylene ethers in the presence of an alkanesulfonic acid as catalyst. Oligo- or polyalkylene ether-modified polydimethylsiloxanes obtainable through this process are suitable as defoamers, as wetting agents, and as additives in coating material formulations.
摘要:
The present invention relates to novel polymer compositions which are obtained by neutralizing a polymer P having at least one functional moiety of the formula (I) bound to at least one of the termini and/or to the backbone of the polymer, with an oligomeric or polymeric amine PA having at least 2 amino groups per oligomer or polymer molecule.
