Claim 0:
1. A method for producing a high viscosity, low volatiles blown polymerized plant-based oil, the method comprising the steps of:
(a) obtaining a plant-based oil;
(b) heating the plant-based oil to a temperate of from about 100° C. to 120° C.;
(c) passing air through the heated plant-based oil to produce a blown plant-based oil having a viscosity of at least 50 cSt at 40° C.;
(d) stripping the blown plant-based oil at a temperature of from about 230° C. to about 270° C. to reduce an acid value of the blown oil to less than 5.0 mg KOH/gram;
(e) adding glycerin during step (d); and
(f) producing a polymerized plant-based oil having a viscosity at 40° C. of at least about 300 cSt.
