Description :
A novel chain stoppered alkyd with 17.5 percent oil length has been synthesized using benzoic acid and rosin as chain stoppers. The heating schedule was over a range of temperatures 170-2450 C for 8 to 11.5 hours. The order of addition and procedural details has been worked out .Alkyd emulsion pastes containing this novel resin, poly vinyl alcohol, water and small quantity of organic solvents have been formulated. These emulsion pastes have storage stability of six months. The above emulsion pastes was used for the formulations of finishing paints. The prepared compositions are on par or sometimes better than commercial samples. They are economical ,technically sound and ecofriendly..
Keywords: Alkyd resin, emulsion pastes, finishing paints.
