The objective of this research was to investigate the miscibility behavior of melamine-formaldehyde (MF) resin and poly (vinyl acetate) (PVAc) blends, for the adhesion between fancy veneer and plywood in engineered flooring, by DSC, TGA and Fourier transform infrared spectroscopy. Blends of various compositions of MF resin/PVAc were prepared to determine and compare the effect of PVAc content. These blends displayed a single curing temperature over the entire range of compositions indicating that this blend system is miscible in the amorphous phase due to the formation of hydrogen bonding between hydroxyl groups of phenolic resin and carbonyl groups of PVAc. The MF resin/PVAc blends were miscible in the amorphous phase over the entire range of compositions. |
