Preparation of oil absorption materials based on styrene and lauryl methacylate by the suspension method

Abstract

The oil absorption materials were prepared by the suspension copoly-merization of styrene(St), lauryl methacrylate(LMA) and divinylbenzene (DVB) as crosslinker. Some effect factors on the absorbency such as: monomer ratio, initiator concentration and crosslinker concentration were studied. The optimal conditions were as following: ratio of styrene/lauryl methacrylate 6/4 (w/w), 1.2 wt% BPO, 0.3 wt% DVB, temperature 90^oC and time 4h. The oil absorbency of materials in different solvents was also investigated
