The main factors which initiate or accelerate degradation of all plastics have been identified as light, especially high-energy ultraviolet radiation, heat, oxygen and water. Conservators consider two approaches to conservation when planning treatment to extend the useful lifetime of all materials, namely preventive and interventive. Preventive conservation may be defined as the mitigation of degradation and damage to cultural property through the formulation and implementation of policies and procedures for storage, exhibition, packing, transport, and use, integrated pest management, disaster management and reformatting or duplication (American Institute for Conservation of Artistic and Historic Works, 15 16 C O N S E R VAT I O N O F P L A S T I C S 1997).

Fawcett and Gibson, the chemists involved in the research project, noticed the formation of a white, waxy solid when ethylene gas was used in experiments. The solid was identified as polyethylene. In trying to reproduce the polymerization, it was discovered that oxygen was necessary for the reaction to take place and had only been present due to a leak in the original apparatus.
