“…[1][2][3] However, it is not exempt from drawbacks such as low modulus, poor thermal stability and impact resistance, which may impose some limitations on its applications. 4,5 Thus, attempts have been made to impart required properties (e.g., toughness, modulus and heat resistance) to the PVC materials by incorporating various llers into the PVC matrix.…”

Six new polyether titanate coupling agents with different polyethyleneglycol (PEG) segment lengths were prepared in this study and were then used to modify calcium sulfate whiskers (CSWs) in order to improve the compatibility between CSWs and poly(vinyl chloride) (PVC). The chemical structure of these coupling agents was characterized by FTIR, Raman, 1 H NMR and 31 P NMR, and the surface properties of CSWs modified by the coupling agents (mCSWs) were characterized by FTIR, SEM-EDS and XPS. Then, CSW/ PVC and mCSW/PVC composites were prepared using a two-roll mill, and their mechanical and thermal properties were characterized to investigate the effects of the PEG segment length of the coupling agents on the performance and compatibility of the composites. The results show that the new coupling agents can significantly improve the compatibility and the interfacial adhesion between CSWs and the PVC matrix, which results in a significant improvement of the comprehensive performance of mCSW/ PVC composites. PEG4000 shows the best modification effect on CSWs. Finally, the underlying mechanisms are discussed.

“…It is a vinyl polymer composing of numerous repeating units of CH 2 -CHCl. www.intechopen.com PVC is mainly produced by radical polymerization (Endo K, 2002). In this polymerization, it associates the vinyl chloride molecules and thus forms the polymeric chains of macromolecules.…”

Aiming to improve the inferior properties of polyvinyl chloride polymer, (BaTiO 3 ) x (PVC) 100-x composite samples were prepared and investigated. The structural changes of the composite (BaTiO 3 ) x (PVC) 100-x were studied as a function of BT content using FTIR, XRD and DSC measurements. Attention is paid to the tetragonality changes during composition changes.It was found that the hindrance to the PVC crystallization becomes less and less serious with the increase of BT ratio in the composite. This behavior could be attributed to the interaction between Ba +2 ions and Chlorine in the polymer. The FTIR spectra indicate a clear interaction between PVC and BaTiO 3 particles as is concluded from XRD results.The Scherrer formula was used to estimate the grain size for the included BT in the (BT) x (PVC) 100-x composite samples. The composite samples show abnormally small tetragonality for its BT content less than unity (с/a < 1). It seems that in (BaTiO 3 ) x (PVC) 100-x composite samples, the stress that stabilized the tetragonal phase of the core regions of BT decreased, leading to lower tetragonality (c/a ratio). It seems that T g of the composite samples increases with the increase of its BT content. Also DSC results reveal the increase of crystallization with the increase of BT content in the composite.
