Declarations under Rule 4.17: as to applicant's entitlement to apply for and be granted a patent (Rule 4.17(ii)) as to the applicant's entitlement to claim the priority of the earlier application (Rule 4.17(iii)) Published: with international search report (Art. 21(3)) (54) Title: SINGLE-SITE CATALYST POLYOLEFIN POLYMERIZATION PROCESS Main Loop Reactors (57) : Disclosed is a method for polymerizing olefms comprising passing a heterogeneous single-site catalyst to a solution or slurry polymerization reactor in the absence of pre-polymerization, wherein the polymerization reactor operates at a temperature of at least 50°C. The heterogeneous single-site catalyst may be suspended and/or dissolved in a solvent selected from the group consisting of oils, aliphatic hydrocarbons and mixtures thereof. Also, the heterogeneous single-site catalyst may be passed to the polymerization reactor at a velocity of greater than 1 m/s or 3 m/s.
