Abstract

The chemical reaction between polyvinyl alcohol (PVA) and tri (dioctylpyrophosphoryloxy) isopropyl titanate (NDZ-201) was studied using X-ray photoelectron spectroscopy (XPS). The results show that some C−OH functional groups of PVA react with the titanate coupling agent to form C_PVA−O−Ti−O−C_PVA bond. The cross-linking of the PVA chains occurs through the formation of C_PVA−O−Ti−O−C_PVA bonds and produces a three dimensional hydrophobic polymer network. Accordingly, the mechanism is proposed that the titanate coupling agent improves the noisture sensitivity of high alumina cement/polyvinyl alcohol (HAC/PVA) based macro defect free (MDF) composite material.
