ConclusionsThe polyallyl alcohols were found to be typical polyhydroxy compounds in esterification reactions with soybean, linseed, and rosin acids. Alcoholysis of soybean oil to give mixed glycerol‐polyallyl esters procceded only with simpler polyols whose size did not exceed an average of 9.5 allyl alcohol units. Polyallyl alcohol proved to be an excellent oil upgrader, the mixed glyceryl polyallyl esters of soybean oil at a 10–15% polyallyl alcohol level were superior to linseed oil in film properties. Complete soybean or linseed esters containing 21–25% of polyallyl alcohol were found to be superior to standard soybean and linseed varnish oils in 30‐gal. pentaerythritol ester gum varnishes and equivalent to dehydrated castor in short length maleic resin varnishes. A soybean fatty acid‐rosin polyester prepared from 47.1% of fatty acids, 31.4% polymerized rosin and 21.5% of polyallyl alcohol X‐101 was equivalent to a soybean oil copolymer or a medium oil length castor alkyd as a baking enamel vehicle.
