Abstract

Summary Synthetic oils have been prepared from residual dimerized fat acids with soybean and linseed fat acids by esterification with polyalcohols, and with or without maleic anhydride or phthalic anhydride. Preliminary evaluation indicates that these oils give films which dry faster and are more resistant to water and alkali than linseed oil films. This enhancement of water and alkali resistance may result from an increase in C‐C bonds present in the films. Ester gum varnishes made from these oils were not markedly superior to similar varnishes made from linseed oil.
