Monomer transport influences in the nascent polymerization of ethylene by silica-supported chromium oxide catalyst

Transport influences during nascent ethylene polymerization over Phillips chromium oxide--silica catalyst were evaluated by using pulse solid--gas chromatography. Measures of effective intraparticle diffusivity and tracer-accessible intraparticle void space were made using helium as a tracer. Measur...
