摘　　要：为改善梳形聚醚-聚甲基丙烯酸甲氧基多缩乙二醇酯[P(CH_1=C(CH_3)CO(OCH_2CH_2)_nOCH_3),n=8,22,分子量分别为400,1000,简称PMEO_8,PMEO2_(22)的力学性能,作者曾用等离子体引发聚合代替自由基引发聚合制备了PMEO_8,PMEO_(22)及其与丙烯酰胺(AM),甲基丙烯酰胺(MA)的共聚物,取得了较满意的结果。The copolyethers of methoxy polyethylene glycol methacrylate (MEO_(16))with acrylamide derivatives, such as methylacrylamide (MA), N,N dimethylacrylamide (DMA), and N, N-diethylacrylamide (DEA), were prepared by plasma-initiated polymerization. The order of conversion of the acrylamides is as follows: MA>DMA>DEA. The crystallinities(Xc) and the glass transition temperatures (Tg) of the copolyethers became lower after the addition of the acrylamides.The relations between the compsition of the P(MEO_(16)-DMA) and the Xc, the Tg were discussed, The ionic conductivity of the P(MEO_(16)-DMA)-LiClO_4is 5.5×10^(-5)S·cm^(-1) when the content of DMA is about 50mol% and the EO/Li is about 32 at 25℃, but that of the PMEO_(16)-LiClO_4 is 1.89×10^(-5)S·cm^(-1) at the same conditions.
