Novel Polyesteramide Resin from Rubber Seed Oil for Surface Coating Application

Abstract

This paper reports the synthesis of rubber seed oil-based polyesteramide via maleinised rubber seed oil intermediate. Rubber seed oil was modified by treatment with maleic anhydride and subsequently reacted with diethanolamine. The synthesized intermediate and the resin were characterized by measurement of physico-chemical properties (acid value, iodine value, and saponification value), resistance to chemicals (water, dilute alkali, dilute acid, and brine) and drying time in comparison with medium oil-modified alkyd resin. The values of the measurement parameter suggest a potential for the application of polyesteramide resin in surface coating applications.
