pe grafted with maleic anhydride

Blends of thermoplastic polyurethane and maleic-anhydride grafted ...Abstract. Thermoplastic polyurethane elastomers (TPU) and polyethylene (pe) form immiscible blends with an extremely low compatibility. In order to improve the dispersion, stability, and properties of these blends, polyethylene was grafted with maleic anhydride (pe-g-MA). Subsequently, it was blended with a commercial polyester - type TPU in a twin-screw extruder. wi

Grafting of maleic anhydride onto linear polyethylene: A Monte Carlo ...4 Oct 2004 ... Abstract. Monte Carlo simulation was used to study the graft of maleic anhydride (MAH) onto linear polyethylene (pe-g-MAH) initiated by dicumyl peroxide (DCP). Simulation results revealed that major MAH monomers attached onto pe chains as branched graft at higher MAH content. However, at extremely low MAH content, the fraction of bridged graft was very close to that of branched graft. This conclusion was somewhat different from the conventional viewpoint, ...

Microstructure of Maleic Anhydride Grafted Polyethylene by High ...7 Jun 2003 ... The microstructure of maleic anhydride (MA) grafted polyethylene (pe), MA-g-pe, has been successfully characterized by high-resolution NMR and FT-IR spectroscopy. The carbonyl asymmetric and symmetric stretchings of MA-g-pe exhibit lower shifts with an increase in the grafting degree of MA, suggesting stronger inductive interactions between different grafts in a solid state. The <sup>1</sup>H and <sup>13</sup>C NMR spectroscopy of [2,3-<sup>13</sup>C2]MA grafted pe with a low molecular&nbsp;...

Effect of Polyethylene-Grafted Maleic Anhydride (PE-g-MAH) on ...22 Mar 2010 ... The effect of polyethylene-grafted maleic anhydride (pe-g-MAH) on the tensile properties, morphology and thermal properties of low-density polyethylene (LDpe)/eggshell powder (ESP) composites was studied. LDpe/ESP composites with different eggshell powder content and the addition of pe-g-MAH were prepared with Z-blade mixer at 180°C and rotor speed of 50 rpm. The tensile strength, elongation at break and thermal stability of LDpe/ESP composites with&nbsp;...

A secondary and perhaps more important objective was to determine whether this cccomonomer concept" that involved styrene was sensitive to pe microstructure, in particular, the arnount of terminal unsaturation and branching the pe possessed. To evaluate the influence of these factors, a series of pe's with varying amounts of both terminal unsaturation and branching were selected and evaluated in both an intemal batch&nbsp;...

Effect of Polyethylene Grafted with Maleic Anhydride on Asphalt ...Low-density polyethylene (pe) was grafted with maleic anhydride (MAH) in solution, which was proved by the infrared (IR) spectrum test result. The grafting ratio peaked at 3.3% as the grafting temperature maintained at 90°C. Compared with the pe-modified asphalt, approximately a 5°C increase of the softening point of the pe-MAHmodified asphalt was observed. Once the dosage of the pe-MAH was higher than 3%, the penetration index of the pe-MAHmodified asphalt was&nbsp;...
