ZHAO Yan1,FU Li-hong1*,SUN Gang2(1.School of Light Chemistry and Environment of Engineering,Shandong Institute of Light Industry,Jinan 250353,China;2.Saint Marco(Zhuhai) Leather Goods Co.Ltd.,Zhuhai 521000,China)  
Firstly,cotton cellulose was basified and aged to alkali cellulose,then samples reacted with 3-Chloro-2-Hydroxypropylurea to produce 3-Ureido-2-Hydroxypropyl cellulose.In this paper,aging time of alkali cellulose was confirmed by researching the effect of aging time of alkali cellulose to its ability of withstanding alkali;The effect of temperature,the mass ratio of intermediate to cellulose,time,NaOH concentration on the mass and capacity of product.The result showed that aging time of alkali cellulose should be 60 ℃,the preparation condition optimized of 3-ureido-2-hydroxypropyl cellulose should be the temperature of reaction at 60 ℃,reaction time 3.5~4 h,the mass ratio of intermediate to cellulose should be 5,NaOH concentration should be 1 mol/L.The structure of macromolecule was confirmed by IR.
