PROCESSES FOR PRODUCING POLYMERIZED ROSIN |
摘要 |
A process for efficiently preparing a polymerized rosin through simple preparing steps without using an advanced equipment; and a novel process capable of efficiently and economically preparing a polymerized rosin by reusing a recovered catalyst. Rosin is polymerized in the presence of particles of a copolymer of (a) an ethylenically unsaturated monomer and (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<2>/g, a pore volume of 0.1 to 1 ml/g, an average pore diameter of 100 to 1,500 ANGSTROM and an acidic functional group content of 2.0 to 7.0 milli-equivalent/g. The copolymer is recovered and then reused in the-polymerization of rosin.
