Abstract
This paper aimed to produce the alkaline phenolic resin by the addition of diallyl phthalate into traditional phenolformaldehyde resin. Then the modified resin was characterized using dynamic mechanical analyzer (DMA), differential scanning calorimetry (DSC), fourier transform infrared spectrometer (FTIR) and simultaneous thermal analyzer (STA). The results indicated that: the increase of the diallyl phthalate contributed to the rise of the storage modulus (E) and loss modulus (E), the decrease of the loss factor. Curing temperature also showed a decline trend and was decreased by 5°Cwhen the amount of modifider was 2.5% of the phenol. The improvemnt of Organic ester on curing of alkaline phenolic resin achieved by rapidly promoting resin molecular to generate reactive intermediate quinone methide. The amount of the modifier had little effect on the thermostability of resin, but it reduced the bonding strength of plywood.
