How is polyvinyl acetate made
Web2 apr. 2010 · Polyvinyl Alcohol. Polyvinyl alcohol (PVA) is a hydrophilic synthetic polymer generated by the hydrolysis of poly (vinyl acetate), which is formed by the polymerization of vinyl acetate [73]. This material has been pursued for tissue engineering because it is nontoxic, biocompatible, biodegradable, and widely available [104]. WebThe bonding process takes place under heat and pressure. When laminated under these conditions, the PVB interlayer becomes optically clear and binds the two panes of glass together. Once sealed together, the glass "sandwich" (i.e., laminate) behaves as a single unit and looks like normal glass.
