摘要：
A study was conducted, to synthesize and polymerize a series of alkyl ethers of oligo(ethylene glycol) methacrylates, to clarify the effect of side chain length and ω-functionality on the water solubility and cloud points. The study synthesized a methacrylic acid ester of tetra(ethylene glycol) methyl ether, M4, to increase the hydrophilicity by the longer oligo(ethylene glycol) chain. A series of ethyl ethers of oligo(ethylene glycol) methacrylates, E1-E4, were also polymerized anionically, to demonstrate the the effect of hydrophobic ω-alkyl groups of side chain, compared with the corresponding methyl ethers, M1-M4. It was observed that all the resulting methacrylic acid esters were liquid monomers tat were purified by the column chromatography and the repeating fractional vacuum distillations over CaH2.
