Abstract: Di-component blends of polybutylene (PB) and high-density polyethylene (HDPE) were developed using melt blending technique with a single screw extruder. Compatibilized and uncompatibilized blends of different composition like 30 PB/ 70 HDPE (wt. %), 50 PB/ 50 HDPE (wt. %) and 70 PB/ 30 HDPE (wt. %) were synthesized using high-density polyethylene maleic anhydride (HDPE-g-MAH) and polybutylene maleic anhydride (PB-g-MAH) as compatibilizers. Differential scanning calorimeter (DSC) was used to study the nonisothermal crystallization kinetics of the blends and pure polymers.

The crystallization kinetics parameters were determined using polymath. And statistical analysis using r2 and 45° plots indicated that the kinetics parameters obtained using Avrami model is the best. Thermogravimetric analyzer (TGA) was also used to study the nonisothermal degradation kinetics of the blends. A nitrogen atmosphere was used at four different heating rates (5, 10, 15 and 20 oC/min) in this work.

The temperature peaks at the maximum weight loss rate changed with increasing heating rate in the DTG thermograms. The kinetics parameters calculated by Kissinger method were the same for the degradation operation. For FWO and KAS methods, experimental results showed that values of kinetic parameters are different for all the conversions. The morphological characteristics of the blends were analyzed using scanning electron microscopy (SEM). SEM investigation showed that the amount of HDPE affects the degree of immiscibility.
