Abstract
Sheets of polycarbonate subjected to natural aging on outdoor exposure showed surface microfissures after 23 months. Changes in the polymer molecular weight were studied by gel permation chromotography and tensile changes. A reduction in molecular weight is verified due to a break in the macromolecular chains by the UV rays. G.G.A. -- AATA -- AATA
