Abstract
Abstract An ungelled polymeric reaction product is prepared by a semi-continuous process. The process involves the vinyl addition polymerization of a vinyl monomer component at a temperature of at least 150°C and under essentially atmospheric conditions. The polymerization is conducted in the presence of a diluent having a molecular weight of at least 200. The ungelled polymeric reaction product can be used as the film forming binder for coating compositions.
