| Abstract: | Increased elastic modulus and ultimate stress of low density polyethylene has been achieved by incorporating coco-yam, water-yam and guinea-com starches into low density polyethylene using a standard hot-melt compounding technique. Some mechanical properties of compression moulded dumb bell shaped films of low density polyethylene containing up to a maximum of 20 wt % of each starch is reported. Evidence is offered using IR spectroscopy linking the degradation of the low density polyethylene/starch composites in compost to an initial break down of the starch by micro-organism in the soil probably followed by diffusion of unsaturated lipids from the compost into the porous polymer which then leads to degradation by auto-oxidation. |
