Copolymerization of turkish tall oil specimens with indene–coumarone. II. Production and properties of indene–coumarone modified tall oil varnishes

Abstract

AbstractTwo varieties of tall oil were copolymerized with indene–coumarone and subsequently esterified with ethylene glycol, glycerol, and pentaerythritol in addition to these esters, Urethanes were also obtained by reacting pentaerythritol esters of copolymers with toluene diisocyanate (TDI). These resultant products were evaluated as varnish vehicles and their film properties were compared with some standard formulation of tall‐oil‐ and vegetable‐oil‐based varnishes. The effect of indene–coumarone content of copolymer on the film properties of final products were additionally studied. Film evaluation showed that these copolymer‐based varnish vehicles could be used in the field of organic surface coating.
