Abstract Composites of nano‐sized barium titanate (BaTiO 3 ) with volume fractions up to 0.5 and poly(butylene terephthalate) (PBT) or linear low‐density polyethylene (LLDPE) were made via extrusion. Scanning electron microscopy demonstrated that BaTiO is well dispersed in the polymer matrices. The crystalline content (DSC) thermal stability (TGA) both polymers decreased increasing loading. Die...

Polyolefins account for 60% of global plastic consumption, but many potential applications of polyolefins require that their properties, such as compatibility with polar polymers, adhesion, gas permeability, and surface wetting, be improved. A strategy to overcome these deficiencies would involve the introduction of polar functionalities onto the polymer chain. Here, we describe the Ni-catalyze...

Abstract Polyethylene based carbon fibers were studied using high density polyethylene(HDPE) and linear low polyethylene(LLDPE) with various melt flow index. The draw ratio of the polyethylene sulfonation mechanism investigated under hydrostatic pressures 1 5 bar in first time. influence index types on reaction was studied. Carbon prepared through LLDPE possessing side chains a fibers, which ex...

a linear low density polyethylene (lldpe) production process, including two- fuidized bed reactors in series (fbrs) and other process equipment, was completely simulated by aspen polymer plus software. fluidized bed reactors were considered as continuous stirred tank reactors (cstr consisted of polymer and gas phases). poly-srk and nrtl-rk equations of state were used to describe polymer and no...

Abstract The steady-state shear viscosity η ( γ ̇ stretchy="false">) \eta (\dot{\gamma }) is required in controlling processing parameters for the extrusion of polymer melts. A new method, so-called ramp test , investigated...
