Abstract:
1. Polymer comprising units derived from ethylene, said polymer having: a) a Melt Index of from 0.05 to 20 g/10 min, as determined by ASTM-1238 Condition E; b) at least 10 per 1000 C-atoms of C1- to C5 short chain branches as determined by C13 NMR, and 1 to 3.5 mol % of units derived from a copolymerizable ethylenically unsaturated ester; c) a density of from 0.90 to 0.94 g/cm d) a rheological relaxation time of at least 10 s, wherein the polymer is obtained by free radical polymerization using an α-olefin chain transfer agent.
