摘要

A new reactive graft copolymer

poly(tetramthylene glycol) - graft-w-propyl sodiumsulfonate-poly(ethylene glycol) (PTMG-g-PEG-CH2CH2CH2SO3-Na+)

was synthesizedby the cationic polymerization of a-w-bifunctional PEG macromonomer (O?CH2—PEG——CH2 CH2 CH2 SO3 Na) and THF. The obtained copolymer exhibits the expected structureas indicated by the result of characterization. Two amino acids (L-arginine

L-tyrosine)were covalently attached to the copolymer after converting the sulfonate group to sulfonyl chloride.So the new reactive graft copolymer(PTMG-g-PEG-CH2CH2SO3-Na+) is expected to be very useful in attachment of potentially bioactive moieties to polymer via a hydrophilic PEG spacer.
