Resumen:
A closcd-loop strategy for copolymer composition control in semicontinuous emulsion polymerization systems is presentcd. This strategy is based on a non-linear adaptive plus proporcional-integral controller that calculates the flow cate of the more reactive monomcr to be added loto the reactor to produce a copolymer of a given composition. The non-linear adaptivc pan of the controller is based on a simplified mathematical model of the process that includcs an on-lino adjustable paramcter. The controller was checked by computer simulation and also cxperimentally verificd during the semicontinuous emulsion copolymerization of ethyl acrylate and methyl methacrylate carried out in a computer controlled experimental sctup using both purifled and tcchnlcal grade monomers.
