Abstract:
An ethylene polymer having the following properties:(i) a density in the range of from 0.90 to 0.98 g/cm.sup.3,(ii) a melt flow rate, as measured at 190.degree. C. under a load of 2.16 kg, in the range of from 0.001 to 3,000 g/10 min,(iii) a melt tension (MT) and melt flow rate (MFR) which satisfies the relationship represented by the formula:logMT.gtoreq.-0.4 logMFR+0.75,(iv) a molecular weight distribution Mw/Mn in the range of from 2 to 9,(v) a molecular weight distribution Mz/Mw in the range of from 2 to 5,(vi) a g* value, which is an index of a proportion of long-chain branches, in the range of from 0.90 to 1.00, and(vii) a swell ratio in the range of from 1.20 to 1.35.
