A method of forming a polymer matrix composite using a soluble derivative of a poly (aryl ether ketone) (PAEK). The method includes mixing a starting PAEK polymer with a solvent and an acid, said solvent being selected from a group consisting of diethylether, tetrahydrofuran (THF), dioxin, and chlorinated solvents; reacting the PAEK mixture with a Lewis acid and a thiol compound in amounts effective to form a poly (aryl ether thioacetal) compound which comprises at least one thioacetal group; and impregnating a plurality of fibers in a solution comprising said poly (aryl ether thioacetal) compound.

The present specification relates to a polymer and a polymer electrolyte membrane including the same.

The disclosure relates to dendritic polyglycerols (dPG) compounds with carboxyalkyl, sulfyl or sulfonyl functional groups that irreversibly inhibit viral infection (virucidal effect) through multivalent interaction in nanomolar concentration range. While the compounds of the disclosure show virus inhibition in the nanomolar range they show no in-vitro toxicity in the same range of concentration.

Provided is a poly(arylene ether ketone) resin which inhibits reactions such as molecular weight extension and crosslinking in a high-temperature molten state and which is excellent in melt viscosity stability and molding processability. The poly(arylene ether ketone) resin contains an alkylsulfonyl group represented by general formula (1). In the formula, R is an alkyl group containing one to four carbon atoms.

Described herein are methods for delivering an anti-cancer agent to a tumor in a subject. The method involves administering to the subject (i) gold particles and (ii) at least one-anti-cancer agent directly or indirectly bonded to the macromolecule and/or unbound to the macromolecule; and exposing the tumor to light for a sufficient time and wavelength in order for the gold particles to achieve surface plasmon resonance and heating the tumor.
