Tunable, Temperature-Responsive Polynorbornenes with Side Chains Based on an Elastin Peptide Sequence

Abstract

Random copolymers made by living ring-opening metathesis polymerization of norbornene monomers containing either the elastin peptide sequence -(VPGVG)- or pentaethylene glycol (see scheme; Mes=mesityl, pyr=pyridine) exhibit a lower critical solution temperature (LCST). The LCST can be easily modified by varying the ratio of the co-monomers in the polymer feed
