Greatest drawability was studied for blend films with branched low molecular weight polyethylene (B-LMWPE) and ultra-high molecular weight polyethylene (UHMWPE) prepared by gelation/crystallization from solutions. The morphology of B-LMWPE-UHMWPE dry gel film was determined by solid-... 

Blends of LLDPE/PP = 50 50, with or without compatibilizing ethylene-propylene copolymer, EPR, were studied by Dumouhn et al. [1984]. In spite of the expected immiscibihty, the blends showed additivity of properties with good superposition of the stress growth functions in shear and elongation, as well as with the zero deformation rate Trouton ratio, Rj, = 1. In earlier work, blends of medium density PE (MDPE) with small quantities of ultra-high molecular weight polyethylene (UHMWPE) were studied in shear and extension. Again, SH and Rj, = 1 were observed.

Copolymer ethylene-dimethyl-aminoethyl methacrylate (EDAM) with 3.9% DAM side groups and ultra-high molecular weight polyethylene (UHMWPE) were blended in decalin solvent. The hot homogenized solution was poured into an aluminum tray to form gels and the decalin was allowed to evaporate from the... 

Fig. 2 Scanning confocal microscopy images of blend films of ultra-high-molecular-weight polyethylene and 10 wt% EHO-OPPE (see Fig. 1). (a) As prepared film, (b) Uniaxially deformed sample drawn to a draw ratio of 80. Both images were acquired by detecting the polarization direction oriented parallel to the (eventual) deformation direction. Inset shows images acquired by detecting the orthogonal polarization direction. Adapted with permission from [35]. Copyright 2000 American Chemical Society...

High-density polyethylene (HDPE)/ultra-high molecular weight polyethylene (UHMWPE) blends are possible by direct compounding, and use of UHMWPE could improve the impact strength or tensile strain of HDPE. The effect of the UHMWPE content on the mechanical properties of the HDPE/UHMWPE blends is improved by compounding due to homogenisation of the mixture [35-39].

The chapter deals with a brief account of various topics in polyethylene-based blends, composites and nanocomposites. We discuss the different topics such as ultra high molecular weight polyethylene (UHMWPE) for orthopaedics devices, stabilization of irradiated polyethylene by the introduction of antioxidants, polyethylene-based conducting polymer blends and composites, polyethylene composites with hgnocellulosic material, LDH as nanofillers of nanocomposite materials based on polyethylene, ultra high molecular weight polyethylene and its reinforcement/oxidative stability with carbon nanotubes in medical devices, montmorillonite polyethylene nanocomposites, and characterization methods for polyethylene based composites and nanocomposites.
