SYNTHESIS OF PSF-g-PAA AND PSF-g-PNIPAAm AND THE ENVIRONMENTALLY RESPONSIVE PROPERTIES OF THEIR BLEND MEMBRANES
PSF-g-PAA和PSF-g-PNIPAAm的合成及其共混膜的环境响应性研究

To prepare environmentally resporsive(ER) copolymers which are suitable for fabrication of ER polysulfone(PSF) membranes,we designed and synthesized the PSF copolymers with poly(acrylic acid)(PAA) and poly(N-isopropylacrylamide(PNIPAAm) side chains,i.e.PSF-g-PAA and PSF-g-PNIPAAm,respectively.These two comb-like copolymers were synthesized via ATRP by using a chloromethylated polysulfone as macroinitiator.The molar fraction of PAA and PNIPAAm in the resultant copolymers estimated from~1H-NMR is 0.538 and 0....
