Interfacial Surface Properties of Compression Moulded Hydrolysed Polyvinyl Acetate (PVAc) Using Different Release Materials

Understanding the effect surface production has on polymer properties is important in design of advanced materials. The aim this study was to determine how moulding process affected rate hydrolysis and topography, chemistry physicochemistry PVAc moulded, hydrolysed surfaces. Three different mould materials were used produce compression moulded sheets which treated with aqueous NaOH at a range concentrations. Textile sheet demonstrated best results. topography transferred surfaces Kapton release visually smooth lower magnification some pitting higher magnification. Teflon had features from coated stainless steel magnifications linear textile wrinkled appearance irregularly spaced peaks. surfaces, physicochemical parameters. most polar attributes dispersive. It clear that selection material an influence PVAc. Such information for engineering industrial processes.
