  • Patent number: 4447354
    Abstract: Glycerol esters of modified rosin are useful tackifiers in rubber adhesive compositions. Esters made with rosin modified by reducing the abietic acid concentration to 5% or less, will retain tackifying properties for longer periods in storage before use. The esters are prepared by simultaneously disproportionating and esterifying unmodified rosin with glycerol in the presence of p-t-amyl phenol and phosphoric acid, for example.
