Researchers develop inexpensive hydrolyzable polymer
Researchers at the University of Illinois USA have figured out how to reverse the characteristics of a key bonding material—polyurea—providing an inexpensive alternative for a broad number of applications, including packaging.
They developed a class of “hindered urea bond-containing polymeric materials” or “poly(hindered urea)s” (PHUs)—cheap polymers that can be designed to degrade over a specified time period. The PHUs can be made with inexpensive chemical precursors in ambient conditions via simple and clean chemistry with no catalyst or by-products. An article about the research is published in the Journal of American Chemical Society (News Article University of Illinois, 2 December 2014).
