PBT is conventional semi-crystallin engineering polymer with a high dgree and rate of crystallization, good chemical resistance, thermal stability and excellent flow properties.PBT is used in various high volume outomotive, electrical modulus and other engineering applications because it processes good tensile strength , flexural modulus and dimensional stability, especially in water and high resistance to hydrocarbons.However PBT suffers from having low-heat distortion temperature the properties of PBT can be modified in three ways to meet the requirements of specific applications. Compolymerization, blending with other polymer such as epoxy to modify properties of PBT that this way.The results of PBT/Epoxy blend sample exhibts tow separate peaks, indicating two phases for this samples. The low molecular wighet epoxy is solable with many of polar thermpoplastics such as PBT and presents an upper critical separation type phase diagram.(UCST)The Tensile test points that in PBT/Epoxy blend sample by addition curing agent increases tensile modulus.
