Research on the Block Copolymer Consisting Fatty Alcohol, Polyether Acrylate and Acrylamide and its Solution Characters

本文合成了脂肪醇嵌段聚醚丙烯酸酯单体 ,并与丙烯酰胺共聚 ,得到共聚物PEPO PAM。芘荧光光谱分析表明 ,该聚合物在水溶液中依靠分子链上的疏水基团形成一定的缔合作用。PEPO PAM相对于部分水解聚丙烯酰胺 (HPAM )具有更好的增粘性。通过调整分子的组成 ,可使该聚合物不仅具有较强的增粘性 ,同时具有良好的水溶性。

In this paper, a block monomer consisting fatty alcohol polyether and acrylate has been synthesized. This monomer co polymerized with acrylamide, then a copolymer PEPO PAM was obtained. The pyrene fluorescence spectrum shows that depending on the hydrophobic group connected with the main polymer chain hydrophobic association is formed in the aqueous solution. The PEPO PAM has higher viscosity than the HPAM. Through changing the composition of molecule, the polymer exhibiting not only higher viscosity but also good solubility can be obtained.
