[0083] Calculation of Branching Probability
[0084] The branching probability is calculated by the following equation:
[0085] BP = 100 × a b
[0086] where "BP" is the branching probability in percent, "a" is the total equivalent weight of polyfunctional monomers with more than 2 reactive groups per molecule, and "b" is the total equivalent weight of all monomers. C.J.Hawker, R.Lee, J.M.J.Frechet, J.Am.Chem.Soc. 113, 4583, 1991 describe an analytical method using NMR to describe the degree of branching based on dendritic units, terminal units and The measured value of the linear unit.

[0093] Three batches of alkyd resin were prepared by the following method. The initial charge to the reactor was 174 grams of TMP, 425 grams of PE, 2351 grams of soybean oil, and DBTO catalyst (1000 ppm). These feeds were heated to an internal temperature of 232°C over 4 hours under a nitrogen blanket and maintained at this temperature to complete the alcoholysis step to form monoglycerides. After a positive test of monoglyceride dissolution in methanol, the internal temperature was lowered to 150-160°C. The reactor was then opened and charged with 950 grams of IPA and 220 milliliters of xylene. The reactor was heated to 220°C within 3 hours. At this point, remove the packed column and check the acid number. Acid values are based on titration with 0.1N KOH in a 50 / 50 xylene / isopropanol solvent mixture with phenolphthalein as the endpoint. The resin product was clear and no longer cloudy, with an acid value of 20 mg KOH / g. The internal temperature was maintained at 220-2...

[0095] The initial charge to the reactor was 749.7 grams of sunflower oil, 660.1 grams of TMP, 1.5 grams of MBTO and 1.5 grams of DBTO. These feeds were heated to an internal temperature of 232°C over 4 hours under a nitrogen blanket and maintained at this temperature to complete the alcoholysis step to form monoglycerides. After a positive test of monoglyceride dissolution in methanol, the internal temperature was lowered to 150-160°C. The reactor was then opened and charged with 144.0 grams of benzoic acid and 750.0 grams of phthalic anhydride. The reactor was heated to 220°C within 3 hours. At this point, remove the packed column and check the acid value. Acid values are based on titration with 0.1N KOH in a 50 / 50 xylene / isopropanol solvent mixture with phenolphthalein as the endpoint. The resin product was clear and no longer cloudy, with an acid number of 11.6 mg KOH / g. The internal temperature was maintained at 220-225°C until the acid number reached close to 10. ...
