DEFINITION

Classification: 554/25

(under subclass 24) Processes which are directed to polymerizing an oil, such as by heating or oxidizing, and the polymerized products resulting therefrom.

(1) Note. Included herein are synthetic drying products resulting from, for example, the interaction of unsaturated fatty acid oils and polyhydric alcohol polyesters of aromatic polycarboxylic acids.

(2) Note. The process of thermally polymerizing oils is commonly termed "bodying" of oils and the resulting products, "bodied oils", which describes oils whose mean molecular weight, specific gravity, and viscosity have been increased by the application of heat.
