Double stimuli-responsive behavior of aliphatic poly(urethane-amine)s derived from supercritical carbon dioxide.


PMID 15856118

Abstract

Copolymeric products from 2-methylaziridine and carbon dioxide showed sharp and rapid phase transitions in response to both temperature and pH; the responsive property can be controlled by varying the reaction conditions whilst maintaining the supercritical state.
