Ethylcellulose acrylonitrile

Fig. 1 Chemical structures of the polymers commonly used for preparation of beads poly (styrene-co-maleic acid) (=PS-MA) poly(methyl methacrylate-co-methacrylic acid) (=PMMA-MA) poly(acrylonitrile-co-acrylic acid) (=PAN-AA) polyvinylchloride (=PVC) polysulfone (=PSulf) ethylcellulose (=EC) cellulose acetate (=CAc) polyacrylamide (=PAAm) poly(sty-rene-Wocfc-vinylpyrrolidone) (=PS-PVP) and Organically modified silica (=Ormosil). PS-MA is commercially available as an anhydride and negative charges on the bead surface are generated during preparation of the beads...

To a very limited extent, other polymers have been coacervated by this process to form microparticles, i.e., ethylcellulose, cellulose nitrate, poly(methyl methacrylate), cellulose acetate phthalate, poly(acrylonitrile-co-styrene), and poly(styrene). " For some of these, liquid poly(butadiene) (8-10 kDa) was employed as a coacervating agent.
