摘要 |
Cross-linked polymers are disclosed which comprise a linear low density ethylene homo - or copolymer which, prior to cross-linking is characterised by a density at 25.degree.C of 0.940 gm/cm3 or less and a linearity expressed in terms of pendant methyl groups per 103 carbon atoms of the polymer chain of less than 30 with a substantial absence of long chain branches. These polymers possess higher .DELTA.T values than conventional branched, low density polyethylenes and are characterised by high elongation versus modulus performance. |
