The catalytic system showed high activity and the polymer with low melting point, narrow molecular weight distribution (MWD) and low crystallinity was produced. %K linear low-density polyethylene (LLDPE) in situ %K poly-merization %K metallocene %U http://link.springer.com/article/10.1007/BF02901130
