POLYMERIC ALPHA-HYDROXY ALDEHYDE AND KETONE REAGENTS AND CONJUGATION METHOD

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.

COPOLYMER COMPRISING AT LEAST THREE BLOCKS: POLYAMIDE BLOCKS, PEG BLOCKS AND OTHER BLOCKS

The present invention relates to elastomeric thermoplastic polymers (ETP) and especially technical polymers with high added value used in varied sectors, such as electronics, motor vehicles or sport. The present invention more particularly relates to copolymers containing polyether blocks and polyamide blocks, abbreviated as PEBA, which have good antistatic properties. Even more particularly, the invention relates to a copolymer containing at least one polyamide (PA) block, at least one polyethylene glycol (PEG) block and at least one block that is more hydrophobic than the PEG block. A subject of the invention is also a process for synthesizing such thermoplastic elastomers which have good antistatic properties and the use thereof in any type of thermoplastic polymer matrix in order to afford this matrix antistatic properties.
