High‐Performance Elastomer with Excellent Resistance to Low Temperature, Aging and Solvent

Abstract Elastomers are essential for a variety of demanding applications, but their performance is significantly compromised under harsh conditions, such as extremely low temperatures and serious aging. Herein, a novel polyurethane elastomer (PFTA) is presented, having perfluoropolyether as the soft segment and catechol‐containing molecules synthesized via Schiff base reaction as the chain extender, where the perfluoropolyether segments confer …
