AB  - Various blend ratios of high-density polyethylene (HDPE) and ultra high molecular 
      weight polyethylene (UHMWPE) were prepared with the objective of determining 
      their suitability as biomaterials. In the unfilled state, a blend of 50/50 
      (HDPE/UHMWPE) ratio by weight was found to yield optimum properties in terms of 
      processability and mechanical properties. Hydroxyapatite (HA) was compounded with 
      the optimum blend ratio. The effects of HA loading, varied from 0 to 50wt% for 
      both filled and unfilled blends were tested for mechanical properties. It was 
      found that the inclusion of HA in the blend led to a remarkable improvement of 
      mechanical properties compared to the unfilled blend. In order to improve the 
      bonding between the polymer blend and the filler, the HA used was chemically 
      treated with a coupling agent known as 3-(trimethoxysiyl) propyl methacrylate and 
      the treated HA was mixed into the blend. The effect of mixing the blend with 
      silane-treated HA also led to an overall improvement of mechanical properties.
