Resorcinol formaldehyde resin was synthesized from resorcinol,styrene and formalde-hyde.Effects of catalyst and reaction conditions on properties of resin were investigated.The results showed that resorcinol formaldehyde resin with softening point of 109 ℃ could be prepared by using p-toluenesulfonic acid as catalyst and adjusting the reaction conditions such as the amount of substances.The vulcanized rubber prepared with resorcinol formaldehyde resin has the same vulcanization and physical properties as the vulcanized rubber prepared with resorcinol,which meets the needs of current radial tire adhesion.
