| Abstract: | The active macromer,polyethylene glycol monomethoxyl ether monoacrylate(MPEGAA),was firstly synthesized using polyethylene glycol monomethoxyl ether(MPEG) and acrylic acid(AA),and the comb poly(acrylic acid)grafted methoxyl polyethylene glycol(PAA-g-MPEG) was synthesized by free radical copolymerization of the active MPEGAA with AA in the presence of sodium sulphite(NaHSO3) as a reducer and chain transfer agent.The structure of the MPEGAA and the PAA-g-MPEG was confirmed through Fourier transform infrared spectrum(FT-IR) and 1H-nuclear magnetic resonance spectrum(1H-NMR) analysis,respectively.The molecular weight of the PAA-g-MPEG decreases with increasing the polymerization temperature and the content of NaHSO3.Results also show that the content of NaHSO3 has a marked effect on the molecular weight of PAA-g-MPEG.The dispersion parameter,polar parameter,hydrogen parameter and solubility parameter of the PAA-g-MPEG are 18.15(J/cm3)1/2,0.82(J/cm3)1/2,10.42(J/cm3)1/2 and 20.94(J/cm3)1/2,respectively. |
