摘要：A red coloured monoazo dye (1-Phenylazo-2-naphthol) has been synthesized from aniline and 2-naphthol at a temperature of 5oC. UV spectrum of the dye showed the presence of azo group and naphthalene chromophores at wavelength of 285-400nm and 200nm respectively. The effect of the dye on the mechanical properties of UPVC film obtained by solvent casting and LDPE film obtained by compression moulding using standard hot melt compounding technique shows that the dye has no significant effect on the tensile properties of UPVC. However, addition of the dye to LDPE reduces the elongation – at – break, ultimate tensile strength and modulus properties.
