THE PROCESS FORMS AT LEAST 30% 1-OCTENE AND A POLYETHYLENE CO-PRODUCT THAT, TOGETHER WITH ANY OTHER REACTION PRODUCTS, REMAINS SUBSTANTIALLY DISSOLVED IN THE LIQUID PHASE. THE POLYETHYLENE CO-PRODUCT HAS A WEIGHT AVERAGE MOLECULAR WEIGHT (MW) OF LESS THAN 200 000 G/MOL, A NUMBER AVERAGE MOLECULAR WEIGHT (MN) OF LESS THAN 3 000 G/MOL, AND A MELT FLOW INDEX OF MORE THAN 20 G/10 MINUTES.
