  Abstract

The ureidopyrimidinone-end functional polycaprolactone with the quadruple hydrogen bonding (UPCL) was synthesized and investigated its plasticizing effect on rigid poly(vinyl chloride) (PVC). The successful polymerization of UPCL was confirmed by nuclear magnetic resonance (NMR) and fourier-transform infrared (FT-IR) spectroscopy. Differential Scanning Calorimetry (DSC) and Dynamic Mechanical Analysis (DMA) showed that UPCL was miscible with PVC at a molecular level. By controlling the mixing amount of UPCL and PVC, the glass transition temperature (Tg) of PVC was able to be controlled from 79 oC to -13 oC, indicating that the rigid PVC was plasticized and became soft. In addition, the results of the tensile test using a universal testing machine (UTM) showed that while PVC had 57% of strain, the plasticized PVC mixed with 50 phr of UPCL showed 342.6% of strain, which was more than 6 times higher than that of PVC. These findings clearly revealed that the incorporation of UPCL can effectively soften and plasticize rigid PVC, presenting a viable approach for the development of flexible PVC materials.
