PREPARATION AND CHARACTERIZATION OF METAL ACRYLATE GRAFTED POLYPROPYLENE

A series of transition metal complexes have been melt grafted to polyp ropylene via a free radical initiated reaction. Significant levels of grafting were achieved. The grafted polypropylenes were coloured. They had glass transition temperatures (T-g) generally higher than the unm odified polypropylene together with lower molecular weights, which sug gested ionomeric behaviour gave rise to these increased glass transiti on temperatures. The surface resistivities of the grafted polypropylen es were all lower than the unmodified polymer which favours improved a ntistatic properties.
