Research on butyl methacrylate-lauryl methacrylate copolymeric fibers for oil absorbency

By adding hydroethyl methacrylate as potential crosslinker, the butyl methacrylate-lauryl methacrylate copolymeric (CPMA) fibers with oil-absorptive function were prepared using heat crosslinking technology after spinning. The effect of monomer feed ratio showed that by controlling the monomer ratio, crosslinker concentration, and crosslinking conditions, the maximum absorbencies of prepared fibers to different oil were 8 g (kerosene)/g (fiber), 15 g (toluene)/g (fiber), and 34.75 g (chloroform)/g (fiber). The structures of fibers were characterized by FTIR, DSC, and SEM. (c) 2006 Wiley Periodicals, Inc.
