Electrical properties of high impact polystyrene (HIPS)/Thermoplastic urethane (TPU) blend with poly(styrene-co-maleic anhydride) as a compatibilzer

초록

This study suggested antistatic material which can increase anti-static properties and mechanical strength by mixing polystyrene for conveying electronic stuffs with metal salt and ester compound as a anti-static agent. We studied about mechanical, thermal and electrical characteristics by changing the contents of MAH of poly (styrene-co-maleic anhydride), compatibilizer. As the result of measuring residue space charge of the blends of HIPS (75)/TPU (25)/poly (styrene-co-maleic anhydride) (MAH weight ratio : 25, 32, 43.5wt%), we could find small residue charge in the blend which MAH(25 wt%) was added and it showed the highest values in tensile strength. Additionally we found out the material to which compatibilizer was added kept better anti-static properties than one to which compatibitizer was not added. In the event we could confirm that the adding of PS-co-MAH enables two polymers were mixed well when HIPS/TPU was blended and anti-static agent made easier dissipative in the blend.
