Polymeric plasticisers gained considerable success in PVC formulations in the early eighties and there are now several manufacturers of plasticising additives based on polymeric compositions in the USA. The good performance of these additives has been considered in the technical literature. For epoxy polymeric plasticisers, an improvement of heat and U.V. stability was also observed as a function of the oxirane oxygen content in formulations. In this paper we refer to some experimental tests on thermal and U.V. light stabilising action of linear low molecular polyesters, based on glycols and dibasic aliphatic acids, which possess a good plasticising effect and low toxicity. Creep tests and calculations of isochronous creep modulii were used to evaluate the stability of PVC formulations.
