Abstract

Wood polyacrylonitrile composite WPC from neem and cork woods were synthesized The process was carried out through benzoyl peroxide 0 05mol l catalyzed impregnation polymerization of acrylonitrile 2mol l 4mol l 6mol l into neem and cork woods in benzene medium at 75 -10c The properties of WPC over untreated wood was evaluated Loading of PAN into cork woods as ascertained through TGA DTGA and DTA as well as Scanning Electron Microscopy SEM was found to increase the resistance against thermo-oxidation of WPCs in comparison to untreated wood Themogravimteric analysis TGA is one of the techniques used to determine the thermal properties of wood Wood polyacrylonitrile composite WPC from mango and cork wood was synthesized The process was carried out through benzoyl peroxide 0 05mol l catalyzed impregnation polymerization of acrylonitrile 4mol l 6mol l into cork wood and mango wood in benzene medium at 75 -10c The properties of WPCs over untreated woods were evaluated in terms of Thermo gravimetric analysis TGA in Nitrogen Thermo gravimetric analysis were improved with impregnation of polyacrylonitrile Impregnation of polyacrylonitrile PAN into mango cork woods were confirmed through scanning electron microscope In the present research effects have been made to develop such polyacrylonitrile impregnated composites in Benzene medium having improved thermal stability for there commercial exploitation for desirable purposes
