The crystallization of a series of low-density polyethylene (LDPE)-and linear low-density polyethylene (LLDPE)-rich blends was examined using differential scanning calorimetry (DSC). DSC analysis after continuous slow cooling showed a broadening of the LLDPE melt peak and subsequent increase in the
The crystallization studies revealed that the high-density polyethylene (HDPE) and linear low-density polyethylene (LLDPE) formed strong cocrystalline mass when they were melt blended in a single screw extruder. The progress of crystallization was observed through a small-angle light scattering inst
The morphology of isotactic polypropylene (iPP)/linear low-density polyethylene (LLDPE blends, compatibilized with ethylene-propylene block copolymer (EP) and two types of styrene-ethylene/butylene styrene triblock copolymer (SEBS), one containing maleic anhydride, the other no reactive sites, has b
## Abstract Linear low density polyethylene/isotactic polypropylene (LLDPE/iPP) blends, with oriented microfibrils of iPP dispersed in the nearly isotropic LLDPE matrix, has been prepared via melt extrusion drawing and subsequent thermal treatment at 160Β°C to melt LLDPE matrix. The presence of orie
## Abstract Polypropylene (PP) was blended with a linear lowβdensity polyethylene (LLDPE, containing 5% hexene comonomer) over a composition range of 10β90% of PP. The crystallization and morphology of the PPβLLDPE blends were studied by differential scanning calorimetry (DSC), polarized optical mi
