Unformatted text preview: s of Polyester/CS composites were studied. Polyester composites are prepared by inco rporating coconut shell at different content. A catalyst, butanox M60 was used to initiate the polymerization reaction. The results showed that tensile strength, modulus of elasticity, flexural modulus and flexural strength of the composites increased with the increased of the filler content while break elongation of the composites decreased with the increased of the filler content. Scanning electron microscopy (SEM) showed that increased in filler content have increased the tendency of filler-matrix interaction. POLY-P5 THE EFFECT OF BLEND RATIO ON TENSILE PROPERTIES AND MORPHOLOGY OF RECYCLED POLYPROPYLENE/CHLOROPRENE THERMOPLASTIC ELATOMERS B Azra, H Salmah, and D Yusrina School of Materials Engineering, Universiti Malaysia Perlis, Taman Muhibah, 02600 Jejawi, Perlis, Malaysia E-mail: nurulazrabakaruddin@gmail.com Thermoplastic elastomers (TPEs) were prepared from polymer blends of Chloroprene rubber (CR) and recycled polypropylene (RPP). The effects of blend ratio on mechanical properties and morpho logical characteristics of the blends were investigated. The results showed that the tensile strength and modulus of elasticity were decreased in increasing of blend ratio. However the elongation at break was increased. These tensile properties are quite proved by scanning electron microscopy of tensile fractured surfaces. The micrograph SEM showed the Chloroprene -recycled polypropylene has less interfacial interaction. 230 3rd ICYC 2010 Universiti Sains Malaysia POLY-P6 23rd-25th June 2010 DEVELOPMENT OF ENVIRONMENTAL FRIENDLY PRESSURE SENSITIVE ADHESIVES (PSAs) FROM NATURAL RUBBER LATEX MM Siti Fatimah, SN Gan and Y Rosiyah Department of Chemistry, Faculty of Science, University of Malaya, 50603Kuala Lumpur, Malaysia E-mail: shifa414@yahoo.com Environmental friendly products have becomes increasingly important in recent years. This project is environmental concerns and new developments in adhesive technology to create safe systems that reduce the emission of volatile organic compounds (VO...
