水溶液溶液性质以甲氧基聚乙二醇丙烯酸酯(MPEGA)和甲基丙烯酸二甲氨基乙酯(DMAEMA)为单体,偶氮二异丁腈(AIBN)为引发剂,采用反相微乳液法合成了一种疏水缔合型共聚物P(MPEGA-DMAEMA)。采用FT-IR、1H NMR、GPC手段对合成的共聚物进行结构表征,并评价了其水溶液性能。结果表明,合成的共聚物P(MPEGA-DMAEMA)具有较好的...
The composition and structural information of the copolymers were studied by gel permeation chromatography (GPC), 1 H-NMR, and TGA. The critical micellization concentrations (CMCs), as well as thermodynamic parameters for micelle formation, of these water-soluble copolymers were determined at different...

The structure of the poly(DEA-co-DMAEMA) macromonomer was characterized by Nuclear Magnetic Resonance (1H NMR) and Fourier transform infrared spectroscopy (FTIR). The effects of the feed components, temperature, and pH on the swelling behavior of the hydrogels were studied. With the increase of...
The grafted samples were verified by the FTIR-ATR, ~1H and ~(13)C HRMAS NMR and ~(13)C CPMAS NMR spectroscopies; thermal properties were analyzed by TGA and DSC and the stimuli-responsive behavior was studied by DSC.Marco A. Luna-Straffon...
在室温下,采用苄醇钾(BzOK)作引发剂通过氧阴离子聚合方法合成了相对分子质量,嵌段组成均可控且相对分子质量分布窄的两亲嵌段共聚物BzO-MMA-DMAEMA和BzO-MMA-DMAEMA.用1HNMR,FTIR,GPC对共聚物进行表征.比较不同加料次序所获得的嵌段共聚物,发现相同"单体/引发剂"条件下,共聚物的组成完全一致,从而证明MMA和DMAEMA的氧...
