Abstract:
An investigation was made which shows how a plasticizer affects the structure of PVC, not only in intermolecular but also intramolecularly, that is, that the crystallinity of the molecule is changed with change in the plasticizer content. The effect of the type of plasticizer depends on its polarity and solvent capacity. The most favorable properties in the finished product are obtained with a poorly dissolving low temperature plasticizer, such as the sebacates and adipates. It is difficult to predict or judge the effect of a plasticizer in the processing of semirigid PVC products, since rheological effects also play a part there in a series of other after effects of the high processing temperature.
