Polyvinyl chloride - processing and structure

Abstract

Widely different procedures for the processing of PVC have proved themselves and have succeeded in practice on the basis of the special physical and chemical properties of PVC. In this connection a distinction must be made between the processing of plasticized PVC and the relatively difficult processing of rigid PVC. A survey of the most important methods of preparation and processing is given here. The special, rather abnormal properties of PVC in comparison with other thermoplastics are partly. a result of its characteristic structure. The consequences for preparation and processing musttherefore be considered anew. Of course, the globular structure of PVC has an effect on the behaviour of the solid-state material and the melt, too, so that great importance must be attributed to the processes at the parttele interface. © 1977, Walter de Gruyter.
