摘要: Abstract A new model is presented for copolymer composition distributions in a stirred tank reactor with unmixed feed streams. The variant which now explicitly considers the effects of backmixing on popular, lamellar stretch model. It can also be regarded as an application to time-dependent slab geometries droplet diffusion An experimental technique based gradient elution thin-layer chromatography was developed measure distribution styrene-methyl methacrylate copolymers. Results laboratory-scale, showed good agreement statistical or Stockmeyer distribution, thus indicating close approach perfect mixing this small vessel. upper limit initial striation thickness calculated 1 mm.
