A polymeric amine synergist is disclosed herein. An example of the polymeric amine synergist includes an aniline moiety, a polyethylene glycol chain, and an ether linkage attaching one end of the polyethylene glycol chain to the aniline moiety. The polymeric amine synergist may be included in a photo curable ink composition.

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.

The present disclosure is drawn to polymeric amine synergist compositions. The polymeric amine synergist composition can include a polymeric amine synergist including an aminobenzene modified with a polyether chain connecting to the aminobenzene through an ether linkage. The polymeric amine synergist can be present in a reaction product mixture with either i) an aminophenol, or ii) a carbonate base.

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.

A ion-conductive fused-ring quinone polymer includes recurring units of formula (1) and/or (2) below ##STR00001##
wherein each X is independently a single bond or a divalent group, and A.sup.1 and A.sup.2 are each independently an aromatic hydrocarbon ring or an oxygen atom or sulfur atom-containing aromatic heterocycle that forms together with two carbon atoms on a benzoquinone skeleton. This polymer is a material having charge-storing properties which, when used as an electrode active material, is capable of providing a high-performance battery possessing high capacity, high rate characteristics and high cycle characteristics.
