摘要：

The kinetics of crystallization of gutta percha (trans-polyisoprene) were studied both in its native form and as the commercial product currently used for dental purposes. Mixtures of native gutta percha with selected low molecular weight substances (BaSO4, CdSO4, Bi2O3, ZnO), 'Thermoplast'-a commercially formulated plasticizer, and colouring agents were also examined. It was shown that any incompatibility of the aforementioned substances caused an increase in the crystallization rate, while compatibility decreased the rate of crystallization.
