Abstract

A PROCESS FOR MANUFACTURING BIMODAL OLEFIN POLYMERS AND COPOLYMERS HAVING A RATIO BETWEEN LOW MOLECULAR WEIGHT FRACTIONS AND HIGH MOLECULAR WEIGHT FRACTIONS WITHIN THE RANGE OF 40:60-70:30, BY MIXING UNDER SHEAR CONDITIONS 5-50 PER CENT BY WEIGHT OF A LOW MOLECULAR WEIGHT UNIMODAL POLYOLEFIN HAVING A MOLECULAR WEIGHT (Mw) BETWEEN 15,000-30,000, AND 95-50 PER CENT BY WEIGHT OF A BIMODAL POLYOLEFIN HAVING BETWEEN LOW MOLECULAR WEIGHT FRACTIONS AND HIGH MOLECULAR WEIGHT FRACTIONS WITHIN THE RANGE OF 30:70-55:45. ACCORDING TO THE PREFERRED EMBODIMENT THERE IS USED A MULTI-PHASE PROCESS COMPRISING A LOOP REACTOR FOLLOWED BY A GAS-PHASE REACTOR , WHEREIN A PART OF THE PRODUCT COMING OUT FROM THE LOOP REACTOR IS SEPARATED AND COMBINED WITH THE BIMODAL PRODUCT COMING OUT FROM THE GAS-PHASE REACTOR.
