  • Accelerated process for making nonlinear polyesters
    Patent number: 4294736
    Abstract: The reaction rate of the process for making nonlinear polyesters, i.e., conventional alkyds, is accelerated by using relatively large proportions of solvent, e.g., 15-50% by weight of an aromatic or ketonic high boiler, and, optionally, an esterification catalyst, e.g., tin oxalate. The process results in alkyds having more evenly distributed molecular weights with significantly reduced reaction times and at lowered reaction temperatures with consequent energy savings.
