The aim of this thesis is to study the effect of precipitated calcium carbonate (pcc) on the processing behaviour, morphology and mechanical properties of both rigid and cellular PVC. To do this, a number of different grades of pcc have been examined and the effects explained with respect to the particle size, shape and surface coating of the different grades. An important part of the novelty of this work has been the study of pcc grades in PVC stabilised with more environmentally friendly mixed metal (calcium/zinc) stabilizers. They are becoming increasingly important because the PVC industry in Western Europe is committed to phase out lead stabilizers by the year 2015. [Continues.]
