The present invention relates to methods of forming star polymers having configurable architecture in which arms are synthesized by means of living anionic polymerization, with the arms being conjugated with a core, the core comprising m coupling groups, each coupling group having n methylene groups. The invention further relates to star polymers produced therefrom.

Star polymers having a silyl coupling

The present invention relates to a strategy for improving the permeability and solubility of pharmaceuticals, based on adding a chemically modified amino alkyl methacrylate copolymer E, wherein the chemical modification is the quaternization of a fraction of the existing amino alkyl groups.

Quarternization of the additive amino alkylmethacrylate copolymer E for improving permeability and solubility of pharmaceuticals

A novel polymeric initiator is disclosed comprising a dendritic polymer core with at least one initiating functional group as an end group. The dendritic polymeric core is preferably a hyperbranched polymer. The polymeric initiators are useful in radiation curable compositions such as varnishes, lacquers and printing inks and are especially useful in radiation curable inkjet inks.
