Polymerized Rosin<\/strong><\/b><\/h2>\n

OTHER NAME<\/span>:<\/strong><\/b>\u00a0\u00a0<\/strong><\/b>Polymd rosin<\/p>\n

DESCRIPTION<\/strong><\/b><\/span><\/p>\n

Polymerized rosin is made by dissolving rosin in solvent oil and performing a polymerization reaction under the catalysis of acid. After slag removal, neutralization, water washing and clarification, it is refined by fractionation in a distillation tower.<\/p>\n

Due to different choices of catalysts and solvents, there are currently several types of processes, namely:<\/p>\n

A polymerization process using protonic acid (mostly sulfuric acid) as the catalyst and gasoline (mostly 200#, chloroform, etc.) as the solvent.<\/p>\n

A polymerization process using Lewis acid (mostly zinc chloride, boron anhydride, etc.) as the catalyst and gasoline (200#) as the solvent.<\/p>\n

Features<\/strong><\/b><\/span><\/p>\n

\u00d8\u00a0\u00a0It has a high softening point, excellent antioxidant properties, higher viscosity in organic solvents, does not crystallize, and can also be processed into esters or salts for application.<\/p>\n

\u00d8\u00a0\u00a0In adhesives, they often show higher adhesion and initial tack.<\/p>\n

\u00d8\u00a0\u00a0Soluble in ethanol, ether, acetone, toluene, carbon disulfide, dichloroethane, turpentine, petroleum ether, gasoline, oils and alkali solutions. Solubility in gasoline is reduced. Insoluble in cold water, slightly soluble in hot water.<\/p>\n
