Unformatted text preview: Cs). In this project, we made pressure sensitive adhesives (PSAs) directly from latex by using palm oil-based polyester as tackifier resin. Firstly, the alkyd resin was synthesized under fatty acid process by employing fusion cook technique. Three different oil length of alkyd resin namely alk-45, alk-47 and alk-65 were prepared and characterized by FTIR, NMR, TGA, GPC and DSC instruments. Then, the alkyds were converted into stable emulsion through emulsion inversion point method (EIP). Next, rheology test was carried out to characterize the properties of the emulsion. Water-based PSAs were prepared by blending alkyd emulsion with natural rubber latex in different ratios, where the water act as a carrier is evaporated through the air or diffused into the porous substrate. Finally, the blends were coated onto a corona -treated polypropylene with wet adhesives thickness of 12.5 μm. The viscoelasticity behavior of the blends was study by Dynamic mechanical analyzer (DMA). Subsequently, peel test, shear strength and adhesive weight per unit area of the PSA tapes were determined. The tests were done accordance with the American Society for Testing and Materials (ASTM). POLY-P7 EFFECT OF POLYETHYLENE-GRAFT-MALEIC ANHYDRIDE (PE-G-MAH) AS COMPATIBILIZER ON TENSILE PROPERTIES, SWELLING BEHAVIOUR AND MORPHOLOGICAL PROPERTIES OF LOW DENSITY POLYETHYLENE/NATURAL RUBBER/WATER HYACINTH FIBER (EICHHORNIA CRASSIPES) COMPOSITES S.J.
