Vinyl chloide-butyl acrylate copolymer resins were produced by suspension polymerization in an industral 7 m3 polymerization reactor.On the basis of small-scale formulas,the ratios and dosages of dispersants were adjusted,the addtion rate of butyl acrylate was controlled by online real-time tracer and gas chromatography,and process of injecting water during polymerization and improved antiscaling process were adopted.The industrial products obtained conformed to the enterprise standard,and could be applied to the production of PVC profiles as substitutes for ACR.
