摘要: Provided is a method for producing a polymer, comprising: a first step for synthesizing a crude polymer by reacting a monomer containing a pyrimidinetrione structure, an imidazolidinedione structure, or a triazinetrione structure, in an organic solvent in the presence of a quaternary phosphonium salt or quaternary ammonium salt; and a second step for precipitating and separating a purified polymer by mixing a poor solvent with the crude polymer-containing solution obtained in the first step.

摘要: Powder coating resins and coatings made using the powder coating resins are described. The powder coating resins are based on the use of C12 to C23 diesters. The C12 to C23 diesters are reacted with a reactant having an alcohol functionality and an amine functionality to form an intermediate polyol, followed by reaction with a diacid to a carboxylic acid terminated polymer having ester and amide functionality.
