dc.description.abstractPreparation of polymer blends between Poly (trimethylene terephthalate) (PTT) /Polyamide 4 (PA 4) ratio at 50:50, 60:40, 70:30 and 80:20 %wt with Haake rheomix. The results indicated that the polymer blends are less viscosity and rapid flow. Mixing of polymer blends are difficult and can’t be compressed by compression mold machine. Another melt blend technique, twins screw extruder was used replace to Haake rheomix. Twins screw extruder was used to prepare PTT /PA 4 at the ratio of 95/5, 90/10, 85/15 and 80/20 % wt. The effect of additive blend (bond fast) 1, 2, 3, 4 and 5 %wt was studied. The thermal properties of PTT and PA4 by using DSC showed the melting temperatures were 229 and 214.1 °C, respectively. The polymer blends at different ratios with the melting temperature in the range of 214-229 °C. The morphological were test with scanning electron microscopy found that the ratio of PTT/ PA 4 at 95/5 is the most compatible. The effect of additive will increased the compatibility of polymer blends. The quantity of bond fast was not effect on physical properties. However, all of polymer blends were still brittle and could not forming part to test the mechanical properties.en_US
