... a specific reaction to degradation. Ultraviolet radiation must be present for degradation by a photochemical process to occur. Therefore, the absorption properties of the plastic are important in determining the activation spectrum. Figure 1 shows the activation spectrum of polycarbonate, using yellowing...

... the microbial cell. Photochemical or chemical reactions may decrease molecular weight to the point that microbial attack can proceed. Invertebrate attack on films is more selective than microbial decay. Films made by the Otey formulation are consumed by a range of invertebrates, but these organisms would...
