摘　　要：以十八烷基三氯硅烷对超支化聚(胺-酯)进行改性,合成了改性的超支化聚(胺-酯)。将改性前后的超支化聚合物用于吸附二甲基亚硝胺和二苯基亚硝胺。吸附结果表明,聚合物对二甲基亚硝胺和二苯基亚硝胺的吸附率分别为51.3%和11.9%,而改性后的超支化聚合物对二甲基亚硝胺和二苯基亚硝胺的吸附率分别为67.3%和37.2%。Modified hyperbranched poly（amine-ester）s with octadecyltrichlorosilane were prepared.The hyperbranched poly（amine-ester）s and modified hyperbranched poly（amine-ester）s were used as adsorbents in dimethylnitrosamine and nitrosodiphenylamine.The adsorption rate of hyperbranched poly（amine-ester）s for dimethylnitrosamine and nitrosodiphenylamine were 51.3% and 11.9%,respectively.However,The adsorption rate of modified hyperbranched poly（amine-ester）s for dimethylnitrosamine and nitrosodiphenylamine were 67.3% and 37.2%.
