Synthesis Optimization and Performance Test of Environmentally Friendly Renewable Poly(HMA-co-BMA-co-MA) Oil Absorbing Microspheres

Abstract

In this study, butyl methacrylate (BMA), methyl acrylate (MA), cetyl methacrylate (HMA) as monomers, cetyl trimethyl ammonium bromide (CTAB) as dispersant, benzoyl peroxide (BPO) as initiator,N, n-methylene diacrylamide (MBA) as crosslinking agent, A kind of ternary oil absorbing resin was prepared by suspension polymerization. The range of long chain monomer (HMA), initiator (BPO), crosslinking agent (MBA) and surfactant (CTAB) was optimized by single factor experiment, and the best resin Poly (HMA-co-BMA-Co-MA) was obtained by orthogonal experiment design. The structure was analyzed by FR-IR, the microstructure of the resin was observed by SEM, and the stability of the resin was evaluated by TG. The experiment showed that the influence degree of reaction factors was as follows: long chain monomer amount > initiator amount > crosslinking agent amount > dispersant amount. The optimal synthesis conditions were: long chain monomer =25wt%, initiator =1wt%, crosslinking agent =1.1wt%, dispersant =0.030g.
