Study on the Curing Process of Allyl Phenol-Formaldehyde Resin
Allyl phenol-formaldehyde (APF) resin was synthesized by using phenol-formaldehyde (PF) resin and allyl chloride as raw materials and sodium hydroxide as alkali catalyst, and its curing process was investigated. The results showed that APF could not only dissolve in polar solvents, but also dissolve in nonpolar solvent. The APF started curing from around 180°C, and it was higher than PF. The curing took place by polyaddition at allyl double bonds, and a wider controllable curing range of 44°C was obtained. The cured surface of the matrix manifested a continuous phase.
