摘要
P(BMA-St)/OATP as an oil-absorption composite was prepared via suspension polymerization using butyl methacrylate (BMA) and styrene (St) as two monomers and modified attapulgite (OATP) as an additive. The effects of dosages of attapulgite, polyvinyl alcohol (PVA) (dispersant), divinylbenzene (DVB) (crosslinker) and azodiisobutyronitrile (AIBN) (initiator), and monomer mass ratio on composite oil absorbency were investigated, and an optimal condition was determined. When the monomer mass ratio is 7:5, and the amounts of OATP, PVA, DVB and AIBN over the total monomer mass are 3%, 3%, 0.5% and 1%, respectively, the toluene absorbency of the prepared composite can reach to 17.8 g·g-1. Properties such as oil absorbency, oil retention and regenerability of P(BMA-St)/OATP are all better than those of pure P(BMA-St) under same experimental conditions.
