Résumé : |
To meet the requirement of improved durability of an alkyd resin for use in weatherwork paints for superstructure of ships, an attempt has been made to chemically modify castor oil alkyd by graft copolymerisation with methyl methacrylate and butyl methacrylate, in view of their ability to provide polymers with good exterior durability. Characterisation of the experimental resins in respect of physical properties was carried out using instruments namely vapour pressure osmometer, rotational viscometer, universal tensile testing instrument (Instron 1123) and differential scanning calorimeter. Performance of the resins was evaluated using fluorescent UV accelerated weatherometer and multi-head glossmeter. The results reveal substantial improvement in drying and weather resistance properties of castor oil alkyd on graft copolymerisation with both, methyl methacrylate and butyl methacrylate. The improvement in these properties is marginally superior in case of MMA grafted alkyds. MMA modification also enhances the mechanical properties of the grafted castor oil alkyd. |
