Abstract:
    A process for efficiently producing a polymerized rosin through a simple step without the need of an advanced equipment; and a novel process capable of efficiently and economically producing a polymerized rosin by reusing the catalyst recovered. A rosin is polymerized in the presence of particles of a copolymer of (a) an ethylenic monomer with (b) a crosslinking monomer copolymerizable with the monomer (a), the particles having an average particle diameter of 0.1 to 3 mm, a specific surface area of 1 to 70 m
