Room temperature synthesis of non-isocyanate polyurethanes (NIPUs) using highly reactive N-substituted 8-membered cyclic carbonates
(RSC, 2016-02-16)
There is a growing interest to develop green synthetic pathways towards industrially relevant polymers
such as polyurethanes without the use of toxic and dangerous isocyanate monomers. The most promising
route towards ...
Temperature responsive PEG-based polyurethanes “ a la carte”
(Elsevier, 2017-06-22)
Temperature responsive polymers able to alter their chemical or physical properties have been extensively
investigated. Most of these polymers have an alkane polymer backbone with only carbon-carbon
bonds. In this sense, ...
Biodegradable Polycarbonate Iongels for Electrophysiology Measurements
(MDPI, 2018-09)
In recent years, gels based on ionic liquids incorporated into polymer matrices, namely iongels, have emerged as long-term contact media for cutaneous electrophysiology. Iongels possess high ionic conductivity and negligible ...
Catechol End-Functionalized Polylactide by Organocatalyzed Ring-Opening Polymerization
(MDPI, 2018-02-06)
There is a great interest in incorporating catechol moieties into polymers in a controlled manner due to their interesting properties, such as the promotion of adhesion, redox activity or bioactivity. One possibility is ...
Unexpected Synthesis of Segmented Poly(hydroxyurea−urethane)s from Dicyclic Carbonates and Diamines by Organocatalysis
(ACS, 2018-07-17)
A complete study of the effect of different organocatalysts on the step-growth polyaddition of a five-membered
dicyclic carbonate, namely diglycerol dicarbonate, with a poly(ethylene glycol)-based diamine in bulk at 120 ...
Non-Isocyanate Polyurethane Soft Nanoparticles Obtained by Surfactant-Assisted Interfacial Polymerization
(ACS, 2017-01-24)
Polyurethanes (PUs) are considered ideal candidates for drug delivery applications due to their easy synthesis, excellent mechanical properties, and biodegradability. Unfortunately, methods for preparing well-defined PU ...
Isomorphic polyoxyalkylenes copolyethers obtained by copolymerization of aliphatic diols
(American Chemical Society, 2019-05-01)
Isomorphism in random copolymers occurs when comonomer units can crystallize within a single crystalline lattice in the entire composition range. This ideal behavior is rare in random copolymers and only a few examples of ...
Polyether Synthesis by Bulk Self-Condensation of Diols Catalyzed by Non-eutectic Acid Base Organocatalysts
(American Chemical Society, 2019-01-25)
Polyethers constitute a well-established class of polymers covering a wide range of applications from industrial man-ufacturing to nanomedicine. Nevertheless, their industrial implementation is limited to short chain ...
