Peroxide cross-linking of rigid PVC
journal contribution
posted on 2007-05-15, 15:58 authored by Noreen Thomas, Xiaoran ZhengThe optimum conditions for crosslinking rigid PVC with trimethylolpropane
trimethacrylate (TMPTMA) and peroxide have been examined. The extent of
crosslinking was measured by determining gel content by Soxhlet extraction in
tetrahydrofuran. Mechanical properties were measured at 130°C and dynamic
viscoelastic measurements were carried out to detect changes in the glass transition
temperature (Tg). It was found that 15phr of TMPTMA and 0.3 phr of peroxide were
optimum concentrations for maximising the extent of crosslinking, tensile strength
and Tg. The lower moulding temperature of 170°C was preferred to minimise thermal
degradation.
