Table 2. Summary of Calculated Single-Chain Micromechanical Properties of Polymers P1–P3^a.

	P1	P2	P3
chain extensibilityb	2.2	2.2	1.9
fracture energyc	10.9	9.8	8.1

^aThe values are calculated relative to those of mechanochemically inert polyester (black, Figure 3D), all of the same initial strain-free contour length.

^bRatio of chain extensions of polymers P1–P3 and aliphatic polyester at chain fracture.

^cRatio of the area under the force/extension curve of polymers P1–P3 to that of aliphatic polyester up to chain fracture.
