Abstract (en)

[origin: WO9842777A1] Polymer composition comprising a linear low density ethylene copolymer containing about 1-30 mol % of alpha-olefin comonomer and having improved resistance to cross-linking during thermoforming are provided. The ethylene copolymer has a narrow compositional distribution of chain branching as reflected by compositional distribution breadth index of at least 50 % and is stabilized to inhibit cross-linking during thermoforming by the addition of an effective amount of a metal carboxylate of C1-C22 carboxylic acid.
