FTIR characterization of aged XLPE
Polymer Testing, 2006 The effects on macromolecular structure brought about by accelerated ageing in linear and crosslinked polyethylenes were detected and quantitatively monitored by using the ATR-FTIR technique. The thermo-processing conditions used in the preparation of samples with various crosslinking levels lead to the formation of by products such as acetophenone and
