摘要

以甲基丙烯酸甲酯（MMA）、甲基丙烯酸缩水甘油酯（GMA）、丙烯酸六氟丁酯（F6BA）为原料，采用溶液聚合法制备了含氟环氧丙烯酸酯共聚物。采用FT-IR、13C NMR 、DSC和GPC等手段对共聚物的化学结构、玻璃化转变温度和分子量及其分布的分析表明：产物是含氟类环氧丙烯酸酯共聚物，玻璃化转变温度随含氟单体用量的增大而降低，分子量分布较窄，分布指数在1.35～1.65之间。采用JC2000C1静滴接触角/界面张力仪考察了共聚物膜的表面能，发现随着共聚物中氟单体含量的增加，表面能下降，当氟单体含量达到20％时，其表面能降低到38.27 mJ·m-2，吸水率随氟单体用量的增大从18.72％下降至4.55％，耐酸碱性能明显提高，涂膜铅笔硬度从3H下降至2H。

Abstract

Acrylate copolymer containing epoxy and fluorine was prepared by solution polymerization

with methyl methacrylate (MMA)

glycidyl methacrylate (GMA) and hexafluorobutyl acrylate (F6BA) as monomers.The chemical structure

glass transition temperature and molecular weight of the copolymer were studied by FT-IR

13C NMR

DSC and GPC.The result indicated that the product was a copolymer containing epoxy and fluorine and the glass transition temperature decreased with increasing F6BA.The molecular weight distribution of the copolymer was narrow and dispersion index was about from 1.35 to 1.65.Surface properties of the copolymer films were also measured by contact angle measurements (JC2000C1).The results showed that the surface free energies of the copolymer films decreased with increasing F6BA

and reached 38.27 mJ·m-2 at 20%（mass） F6BA.Water absorption of the films reduced from 18.72% to 4.55% with increasing F6BA.The resistance to acid and alkali was improved obviously and the pencil hardness decreased from 3H to 2H.
