摘　　要：在N,N-二甲基甲酰胺中采用脂肪醇聚氧乙烯醚对苯乙烯-马来酸酐共聚物(SMA)进行接枝酯化改性,制备了系列梳状两亲性SMA脂肪醇聚氧乙烯醚单酯钠盐,SMA-g-O-3、SMA-g-O-6、SMA-g-O-10、SMA-g-O-15和SMA-g-O-20,通过红外和GPC分析佐证了接枝酯化的发生。将其应用于皮革复鞣加脂工艺中,研究了SMA钠盐及SMA脂肪醇聚氧乙烯醚单酯钠盐对成革接触角和静态吸水率的影响。结果表明:SMA钠盐及SMA脂肪醇聚氧乙烯醚单酯钠盐处理后的铬鞣胶原纤维,随着乙氧基数目的增加,静态吸水率逐渐提高,而表面接触角逐渐减少。Through the esterification modification of styene maleic anhydride copolymer（SMA） with fatty alcohol-polyoxyethylene ether in the solvent of N,N-dimethylformamide,the surfactants amphiphilic sodium SMA odd-alcohlo esters,namely SMA-g-O-3,SMA-g-O-6,SMA-g-O-10,SMA-g-O-15 and SMA-g-O-20,were prepared.The esterification modification was confirmed by IR and GPC.The esterification extent was estimated by the measurement of the change of acid values before and after the esterification.The effects of different ethyoxyl number fatty alcohol-polyoxyethylene ether modified SMA to the leather contact angle and static bibulous rate were studied with the retanning and fatliquoring test.The results showed that the graft esterification extents were all above 90%.After treatment with SMA modified by fat alcohol ethers single ester sodium salt,the contact angel of the chrome tanned collagen fiber decreased,while the static bibulous rate increased,as the increase of the number of ethyoxyl.
