中文摘要：
采用原子转移自由基聚合（ATRP）方法合成了PtBA—b—F127-b—PtBA（PtBA为聚丙烯酸叔丁酯），经三氟乙酸水解得到PAA—b—F127-b—PAA（PAA为聚丙烯酸）．进一步通过碳二亚胺的水溶性衍生物1-（3-二甲氨基丙基）-3-乙基碳二亚胺盐酸盐（EDC·HCl）在水溶液中成功地耦合β-乳球蛋白（Big）和PAA—b—F127-b—PAA．蛋白的三级构象没有受到反应条件的影响．与纯Big相比，（PAA—b—F127-b—PAA）-Blg复合物的乳化性能大大提高．
英文摘要：
Poly （acrylic acid）-b-F127-b-poly （acrylic acid） （PAA-b-F127-b-PAA） was synthesized through atom transfer radical polymerization （ATRP） in combination with the subsequent hydrolysis of tert-butyl groups using excess trifluoroacetic acid （TFA）. The （PAA-b-F127-b-PAA） -β-lactoglobulin conjugate was successfully syn- thesized using water soluble 1 -ethyl-3- （3-dimethyllaminopropyl） carbodiimide hydrochloride （ EDC · HCl） , a carbodiimide derivative, as the conjugation agent. Fluorescence spectroscopy indicated that the ternary struc- ture of protein was maintained even conjugation to PAA-b-F127-b-PAA. The conjugate exhibited significantly better emulsifying properties than that of pure β-lactoglubulin.
