METHOD FOR MEASURING CONCENTRATION OF PROPYLENE POLYMER SLURRY, AND PROCESS FOR PRODUCING PROPYLENE POLYMER

摘要

A method for measuring a concentration of a propylene polymer slurry contained in a polymerization reactor, in which liquid phase-filled polymerization of propylene or a combination of propylene with a comonomer is carried out, according to the defined formula, slurry concentration = 0.1(QO- QI)/(QPPI); and a process for producing a propylene polymer comprising the step of homopolymerizing propylene or copolymerizing propylene with a comonomer in a liquidphase- filled polymerization reactor while measuring a concentration of a propylene polymer slurry contained in said polymerization reactor according to the above formula.
