Abstract:
A series of poly(ether urethane) networks were synthesized from polyether polyols obtained by ionic-coordinative polymerization of epoxidized methyl oleate (EMO) using 4,4′-methylenebis(phenyl isocyanate) or l-lysine diisocyanate as coupling agents. Moreover, a variety of segmented poly(ether urethane) networks with different hard segment contents were obtained using 1,3-propanediol as the chain extender. The materials were characterized by differential scanning calorimetry, thermogravimetric analysis, dynamic mechanical thermal analysis, and tensile properties. © 2010 Wiley Periodicals, Inc.
