The present disclosure provides a non-hydrocarbyl-based alcohol initiated polyetheramine. In particular, the polyetheramine of the present disclosure is produced from a tetrahydrofurfuryl alcohol-based initiator which is alkoxylated and then reductively aminated. The polyetheramine of the present disclosure may be used in a variety of applications, such as a raw material in the synthesis of a dispersant for use in an aqueous pigment dispersion.

This disclosure relates to polymersomes comprising a crosslinked polymer and their use as drug delivery vehicles. Specifically, polymersomes comprising a polymer of Formula I: ##STR00001##
wherein each R is independently C.sub.1-6 alkyl; and n is an integer between 1 and 50.

Provided herein are polymeric -hydroxy aldehyde or -hydroxy ketone reagents which can be conjugated to amine-containing compounds to form stable conjugates in a single-step reaction. In selected embodiments, the polymeric reagent itself incorporates an internal proton-abstracting (basic) functional group, to promote more efficient reaction. The substituent is appropriately situated, via a linker if necessary, to position the group for proton abstraction, preferably providing a 4- or 5-bond spacing between the abstracting atom and the hydrogen atom on the -carbon. Also provided are methods of using the reagents and stable, solubilized conjugates of the reagents with biologically active compounds. In preferred embodiments, the polymeric component of the reagent or conjugate is a polyethylene glycol.

The present invention concerns a metal or metal alloy deposition composition, particularly a copper or copper alloy deposition composition, for electrolytic deposition of a metal or metal alloy layer, particularly for electrolytic deposition of a copper or copper alloy layer, comprising at least one type of metal ions to be deposited, preferably copper ions, and at least one imidazole based plating compound. The present invention further concerns a method for preparation of the plating compound, the plating compound itself and its use in a metal or metal alloy deposition composition. The inventive metal or metal alloy deposition composition can be preferably used for filling recessed structures, in particular those having higher diameter to depth aspect ratios.
