Formatted abstract
Polyethylene (PE) films have a wide variety of uses, including agriculture. However, disposal of the films is a problem because of large volume that has to be either thrown into landfills or be incinerated. Developments in photo-degradable polymers might be the solution to the problem. These films have a pro-degradant additive that enables the polymer to undergo embrittlement and fragmentation at an accelerated rate. The pro-degradant is designed such that the driving force behind the accelerated degradation is UV light and heat combined. This offers an environmentally safe solution for the agricultural industry for mulching films. Since the films are produced in large amounts, they are stored as large rolls in warehouses awaiting distribution or utilization. As most warehouses are not able to maintain the environment inside, the films are susceptible to oxygen, heat and possibly even UV light. It is possible that the performance of the films would be affected by prolonged storage. While it would be ideal to experiment on all the variables; this project will only cover heat as the experimental variable. In the experiment, films were exposed to elevated temperatures.
