Abstract
AbstractRosin and hydroxymethyl derivatives of rosin acids react rapidly with commercially available glycidyl ethers to give the hydroxy monoesters of aliphatic ethers. These esters of rosin, oxonated rosin and tetrahydroabietic acid are viscous liquids of low acid number and high hydroxyl number with a light to golden amber color. In the case of 12‐hydroxymethyltetrahydroabietic acid, the products are colorless gums of a tacky, semisolid consistency. The acid, hydroxyl and saponification values, and the viscosities and softening points are tabulated.
