HI,

I WAS TRYING TO SYNTHESIS AN AMPHIPHILIC POLYESTER HAVEING BOTH HYDROPHOBIC PART AND HYDROPHILIC PART.

I REACT TETRA PROPENYL SUCCINIC ANHDRIDE (TPSA) AND EPICHLROHYDRIN (ECH) TO FOR A POLYESTER.

SO after getting the polymer, I WANNA ADD POLYETHYLENE GLYCOLMETHYLE ETHER-560 (PEG-ME)TO FORM THE AMPHIPHILIC POLYESTER.

NOTE THAT THE TPSA ACTS AS THE HYDROPHOPHIC PART AND PEG-ME ACT AS THE HYDROPHILIC TAIL.

SO, IN DOING THIS, I WANNA SUBTITUTE THE CHLRONINE ON ECH WITH PEG-ME

I USED TETRA BUTYL AMMONIUM HEXAFLUORO PHOSPHATE AS THE TRASNFERRING AGENT AND SODIUM HYDROXIDE TO NEUTRALIZED THE REACTION.

BUT IM NOT GETTING THE DESIRE PRODUCT.

PLEASE I NEED YOUR SUGGESTIONS.
