摘　　要：为改善淀粉浆料的性能,在碱性条件下,以酸解淀粉(ACS)为原料,十二烯基琥珀酸酯(DDSA)为酯化剂,对十二烯基琥珀酸淀粉酯(SSDS)的合成工艺进行了研究。通过单因素试验,探讨了反应时间、反应温度、体系p H、淀粉乳质量分数和DDSA加入量对取代度的影响。确定的最佳工艺条件为:反应时间为3 h,反应温度为35℃,体系p H为8.5,淀粉乳质量分数为35%,DDSA加入量为酸解淀粉干重的3.75%。此外还比较了十二烯基琥珀酸淀粉酯与酸解淀粉对13 tex T/C65/35经纱的浆纱性能,得出十二烯基琥珀酸淀粉酯浆纱的强伸性、耐磨性、毛羽帖伏性均较好,是一种性能优良的浆料。In order to enhance the sizing properties of starch,the synthetic technology of starch sodium dodecenyl succinate（ SSDS） is estimated. The starch is synthesized by acid hydrolyzed starch（ ACS） with dodecenylsuccinic anhydride（ DDSA） as an esterifying reagent under an alkaline condition. The effects of reaction time,reaction temperature,p H of reaction system,starch concentration and the amount of DDSA on the degrees of substitution are discussed. The experimental results show that the optimum technological conditions are as follows： 3 hours of reaction time,35℃ of temperature,8. 5 of p H,35% of the content of DDSA and 3. 75% of the concentration of starch aqueous dispersion. In addition,tensile strength,breaking elongation,abrasion resistance and hairiness coverage of 13 tex T / C65 /35 warps sized with SSDS are better than those sized with ACS. As a result,SSDS as a sizing agent may show strong sizing properties.
