Binder et al employed two different sets of complementary hydrogen-bonding motifs to cormect phase-separating poly(iso-butylene) and poly(etherketone) in the bulk. The telechelic polymers were synthesized with both sets of hydrogen-bond motifs appended to their respective chain ends, and all polymers were able to yield hydrogen-bonded block copolymers capable of microphase separation. The strongly botmd Hamilton receptor motif (Ka=3 X 1stabilized the material up to 230 ° C, beyond which macrophase separation was observed. [Pg.622]

Supramolecular polymers have been explored as smart materials because of their intrinsic reversibility of the bonds. In the past years, hydrogen bonding has been proven to be the most suitable candidate for applications in supramolecular chemistry. With increasing creation of hydrogen bonding motifs, the exploration of supramolecular polymers formed by multiple hydrogen bonds has been carried out... [Pg.348]
