ETHYLENIC POLYMERS AND PROCESS FOR THE PRODUCTION THEREOF

摘要

A blow-moldable or extrudable ethylene polymer having an excellent moldability which gives a molded product free of roughened surface, having: a number-average molecular weight Mn (V1) as determined from the amount of a terminal vinyl group by <13>C-NMR measurement with respect to a fraction having a number-average molecular weight Mn of 100,000 according to GPC; and a number-average molecular weight Mn (V2) as determined from the amount of a terminal vinyl group by <13>C-NMR measurement with respect to a fraction having a number-average molecular weight Mn of 10,000 according to GPC, Mn(V1) and Mn(V2) satisfying the following relationship: $and\; having\; a\; melt\; flow\; rate\; (HLMFR)\; of\; from\; 0.1\; to\; 70\; g/10\; min.\mathop{\mathrm{image}}$
