The results showed that the fiber had the function of absorbing toluene and trichloroethylene after introducing HEMA into macromolecules, and the absorptive process obeyed Hill equation of sigmoidal model.Toluene and trichloroethylene absorbency increased with the increase of mass fraction of HEMA,and their maximum absorbency was 10 g/g and 21 g/g,respectively.The ratio of remaining fiber also increased with the increase of mass fraction of HEMA to make organic liquid retention ratio strengthen.Furthermore,dynamic mechanical performance of the fiber was affected by mass fraction of HEMA obviously, and the segments movement was influenced more obviously.At the same time,mass fraction of HEMA had a great impact on the surface and cross section morphologies,especially,many cavities existed in surface, and cross section had a lot of holes with asymmetric size when mass fraction of HEMA was equal to 15 wt%.

结果表明，HEMA引入大分子后，所得纤维对有机液体甲苯、三氯乙烯具有吸附功能，且吸附过程符合sigmoidal模型中的Hill方程；随HEMA质量分数的增加，纤维对甲苯和三氯乙烯的饱和吸附量增大，对甲苯和三氯乙烯的最大吸附量分别可达10 g/g和21 g/g；随HEMA质量分数的增加，纤维剩余率增加的同时，使纤维对甲苯和三氯乙烯的握持能力增强；HEMA质量分数对纤维动态力学性能有突出影响，特别是链段运动受其影响更为明显；HEMA质量分数对纤维表面和断面形貌均有显著影响，特别是当HEMA质量分数为15 wt%时，所得纤维表面出现了许多空洞，其断面存在许多尺寸不均的空洞。

A1l the thick adsorption layer,large space steric hindrance,thick solvate layer and stable ξ-potential of ASP adsorbed on cement particles resist the flocculation of cement particles.In addition the early stage hydration of cement is restrained because the—OH ,—NH2 in ASP can suppress the formation of hydrated products such as C-S-H ,Ca2 and ettringite crystals through forming unstable complex compound with Ca2+.So ASP has excellent plasticity-retention capability of concrete.

由于ASP在水泥颗粒表面的吸附层较厚、空间位阻较大、溶剂化层较厚及ξ-电位较稳定等原因，阻碍了水泥颗粒间的凝聚；同时由于ASP含有的—OH，—NH2等官能团与水化产生的Ca2+形成不稳定的络合物，抑制了水化产物C-S-H，Ca2和钙矾石等结晶体的形成，从而抑制了水泥的早期水化，故ASP具有良好的保塑性能。
