Polymerized Rosin is a pale, acidic which composed predominately of dimeric acids derived from rosin with lesser amounts of monomeric resin acids and neutral materials of rosin origin. It has high dimmer contents, light color, high softening point and acid value, no rystallizing, low hot water dissolvable contents, good oil dissolvability and hardly changing the color of lead acetate. The high resistance to oxidation and does not crystallize from solutions or from solid compositions. It is compatible with many natural and synthetic film formers and rubbers. Being an acidic resin, it reacts readily with polyalcohols or hydrated lime to yield high melting derivatives.
