ABSTRACT:
Live polyethylene slurry is treated with small amounts of ethylene in the absence of hydrogen, for example in the drier. By using this procedure it is possible to prepare polymers with very high, controllable levels of swell. In contrast to previous procedures reported for dual stage polymerizations, the melt flow ratios are not appreciably altered.
