Disclosed is a cell pouch having excellent formability, which includes a high elongation nylon film. When the high elongation nylon film is stretched in a machine direction (MD), an increment of a tensile strength value with respect to an increment of an elongation value (an increment of tensile strength/an increment of elongation) increasing from 6.7% to 100% is more than 0.04 and less than 0.05, and when the high elongation nylon film is stretched in a transverse direction (TD), an increment of a tensile strength value with respect to an increment of an elongation value increasing from 6.7% to 100% is more than 0.06 and less than 0.08.

In one aspect, methods of depolymerization are described herein comprising providing a synthetic polymer including a hydroxylated aliphatic backbone or hydroxylated backbone segments, and homolytically activing OH bonds of the hydroxyl groups. Homolytic activation induces the formation of alkoxy radical intermediates followed by CC bond ?-scission events breaking the polymer backbone into depolymerization products. In some embodiments, depolymerization products comprise alkyl radical intermediates reduced by hydrogen atom transfer. Moreover, in some embodiments, the depolymerization products are further reacted into difunctionalized products or comprise functionalities derived from the polymer structure. The difunctionalized products can subsequently be employed in polymerization processes for the production of additional synthetic polymers.
