Isocyanate-free synthesis of (functional) polyureas, polyurethanes, and urethane-containing copolymers

Ubaghs, LucPublikationsserver der RWTH Aachen University2005

… reagents, such as diamines, amino alcohols, diphenyl carbonate, ethylene carbonate, 1,2-propylene carbonate, gamma-butyrolactone, and glycerol. Several synthetic routes using AA- or AB-type monomers are presented, and the polymers obtained are characterized by means of NMR, GPC, DSC, and TGA.

Synthesis and characterization of alternating poly(amide urethane)s

Sharma, BhaskarPublikationsserver der RWTH Aachen University2004

… diamines and carbonic acid derivatives, i.e. diphenyl carbonate and ethylene carbonate as substitutes for phosgene. A new synthesis was developed where the polycondensation of a-hydroxy-w-O-phenyl urethanes and a-hydroxy-w-O-hydroxy ethyl urethanes plays a key role. It was shown that the …
