I 1 42 ,-1 (57) : A method including a) polymerizing at least one monomer in a gas phase reactor in the presence of a supported multi- modal catalyst system to form a multimodal polyethylene product having a reactor split equal to respective weight fractions of resin ei el components in the polyethylene product; b) applying a predetermined formula for a product parameter of the multimodal polyethylene 1-1 product; c) obtaining incorporation data and production rate data from the reaction based upon the predetermined formula; d) determin- Ot 0 ing an actual hydrogen leading indicator; e) comparing the actual hydrogen leading indicator to a target value for a hydrogen leading ---. indicator to determine a deviation of the actual hydrogen leading indicator from the target value; and f) adjusting an amount of a catalyst GC precursor being fed to the gas phase reactor to control reactor split and a product parameter. 1-1 0 ei O [Continued on next page] WO 2018/081226 Al MIDEDIMOMOIDEIREIDIONIMHOHOHOIROMEEN MG, MK, MN, MW, MX, MY, MZ, NA, NG, NI, NO, NZ, OM, PA, PE, PG, PH, PL, PT, QA, RO, RS, RU, RW, SA, SC, SD, SE, SG, SK, SL, SM, ST, SV, SY, TH, TJ, TM, TN, TR, TT, TZ, UA, UG, US, UZ, VC, VN, ZA, ZM, ZW.
