Abstract
In contrast to the known alkyd resins (fatty acid-modified polyesters) produced by way of esterification reaction, the alkyd resins according to this invention are produced by way of successive addition reactions. As a result, the structure and the chain length of the molecules can be predetermined, and the products obtained consist of uniform polyester molecules. Such products have viscosities lower than that of the known alkyd resins, thereby permitting the production of baking varnish systems comprising a low solvent content.
