Tuning polyethylene chain topology via ring incorporation in chain walking ethylene polymerization-Zhibin Ye

we have demonstrated herein the unique linearization effect of ring incorporation on polyethylene chain topology in chain walking polymerization. By controlling the ring content in the polymers via changing the concentration of DEDAM (the ring-forming comonomer) in the polymerization, we can effectively tune polymer chain topology from hyperbranched to linear while without changing ethylene pressure and temperature. Ring incorporation can thus be used as an alternative effective and convenient polymerization strategy for tuning polymer chain topology in chain walking polymerization.
