Extract

When polycarbonate is loaded in tension at room temperature to failure, a certain percentage of the chains are believed to undergo cleavage due to the constraints of entanglements. We present direct evidence that accompanying fracture of polycarbonate, CO molecules are released due to bond scissions.
