Peroxide crosslinking of rigid poly(vinyl chloride)
journal contribution
posted on 2009-07-20, 15:03 authored by J. Anoma G.S.G. Gunewardena, Marianne GilbertPeroxide crosslinking of unplasticised poly(vinyl chloride), PVC with trimethylolpropane
trimethacrylate (TMPTMA) has been investigated. Formulations used in this work contained a nontoxic
lead free stabiliser and showed good colour and heat stability. The samples have been
examined by differential scanning calorimeter(DSC) and tensile properties at room temperature and at
130oC were measured. Gel content or tetrahydrofuran (THF) insoluble material was measured as an
indication of crosslinking. It is shown that premature crosslinking can be avoided during processing.
It was found that 190oC was the optimum processing temperature for maximum gel content. The
residual unsaturation was monitored using FTIR.
