Polyureas are relatively inexpensive and easy to synthesize, plus they tend to be highly resistant to breaking down, making them useful for coatings, adhesives, and other applications requiring durability. Hanze Ying and Jianjun Cheng of the University of Illinois, Urbana-Champaign, have now changed the game for the polymers by designing and synthesizing a class of easily hydrolyzable polyureas (J. Am. Chem. Soc. 2014, DOI: 10.1021/ja5093437). . . .
