Abstract

A tough and transparent norbornene copolymer film affixing an imidazolyl iron–salen complex catalyst exhibited an ultra-high, humidity-independent, and monthly paced oxygen-scavenging capacity up to 300 mL (oxygen gas at STP)/g(film). The homogeneously dispersed and immobilized iron complex in the polymer matrix catalytically contributed to the exceptionally high-yield oxidative consumption of polymer allylic bonds.
