中文摘要：

以甲基丙烯酸十二氟庚酯（FM）、丙烯酸丁酯（BA）、甲基丙烯酰氧乙基三甲基氯化铵（DMC）、N-羟甲基丙烯酰胺（NMA）为原料，制备了白乳化阳离子含氟丙烯酸酯多元共聚物乳液，将w（DMC）=10％、软硬单体比例n（BA）／n（FM）=1．1、w（NMA）=5％时所合成的乳液以质量分数5％进行表面施胶．施胶量为1．2g／m。时，抗油渗透时间为62min，表面强度达4.3m／s。并通过红外光谱（FT-IR）、差示扫描量热（DSC）和透射电镜（TEM）等对乳液性能和共聚物结构进行了表征。结果表明，共聚物玻璃化转变温度为50℃左右，乳液粒子呈规则球形．乳胶粒平均粒径为96～102nm。

英文摘要：

The cationic fluoroacrylate copolymer emulsion was prepared with Methacrylatoethyl trimethyl ammonium chloride （DMC）, butyl acrylate （BA）, and 1H, 1 H,7H-Dodecaftuoroheptyl methacrylate （FM） by copolymerization in aqueous acetone. The paper sized by the fluorinated emulsion showed good oil-resistant ability when w（DMC） = 10%, n（BA）/n（FM） = 1.1, w（NMA） = 5%. The results showed that the oil-resistant time of the paper surface sizing with the diluted dispersion containing 5.0% solid content （mass fraction） and the pick up of 1.2 g/m^2 was more than 62 min and the surface strength was 4.3 m/s. The copolymer was characterized by DSC and FT-IR, the size and distribution of the emulsion particles were investigated by TEM. The results showed that glass transition temperature of the copolymer is 50% and the emulsion particles size is 96 - 102 nm.The cationic self-crosslinking fluorinated acrylate emulsion can increase the oil repellent and surface strength of the paper obviously.
