Resin copolymerized by n-butyl methacrylate (BMA) with β-hydroxyethyl methacrylate (HEMA) was synthesized in polymerization kettle

and functional fiber absorbing organic liquid was prepared by gelation-spinning in a twin screw spinning machine

then the influence of mass fraction of HEMA in monomer feed ratio on swelling behaviors was investigated and dynamic mechanical performance of the fiber was analyzed by dynamic thermomechanmetry (DMA)

finally the surface and cross section morphologies were observed by scanning electron microscopy (SEM).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%.
