Alkyd Resins from Polymerised Rubberseed Oil

Abstract

Rubberseed oil (RSO) was thermally polymerised at different temperatures. It was also polymerised at the same temperature using various percentage of benzoyl peroxide (BPO) and Azobisisobutyronitrile (AIBN) as free radical catalysts. During polymerisation, the free fatty acid content increased as revealed by increasing acid value and unsaturation decreased as indicated by decreasing iodine value. The FFA, unsaturation, viscosity and refractive index of the polymerised oil samples were determined.Alkyd resins were prepared from as it is and polymerised rubberseed oil samples. The physical properties and air dried and baked film properties of these alkyd resins were studied and compared.

Alkyd Resins from Acrylated Prepolymerised Rubberseed Oil

“…improve the initial properties [2]. In our earlier paper [3], we reported the modification of oil by subjecting it to catalytic and thermocatalytic polymerisation by utilizing BPO and AIBN as free radical initiators. In the present study, an attempt has been made to further improve the properties of thermocatalytically polymerised oil by acrylation.…”
