Opportunities for organocatalysis in polymer synthesis via step-growth methods
(Elservier, 2019-03-14)
Organocatalysis has emerged as an invaluable tool for polymer synthesis and has already demonstrated versatility for replacing organometallic catalysts in many polymerization reactions. The overall ease of removal and lower ...
Chemical Structure Drives Memory Effects in the Crystallization of Homopolymers
(ACS, 2020-06-11)
Although the study of melt memory has attracted much interest, the effect of polymer chemical structure on its origin has not been fully elucidated. In this work, we study melt memory effects by Differential Scanning ...
Self-nucleation Effects on Polymer Crystallization
(ACS, 2020-05-28)
The existence of a “memory” of the previous crystalline state, which survives melting and enhances re-crystallization kinetics by a self-nucleation process, is well-known in polymer crystallization studies. Despite being ...
Melt Memory Effects in Poly(butylene succinate) Studied by Differential Fast Scanning Calorimetry
(MDPI, 2020-11-26)
It is widely accepted that melt memory effect on polymer crystallization depends on thermal history of the material, however a systematic study of the different parameters involved in the process has been neglected, so ...
ROP and crystallization behaviour of partially renewable triblock aromaticaliphatic copolymers derived from L-lactide
(Elsevier, 2019-10-26)
Two series of partially biobased ABA triblock copolyesters were successfully prepared by ring-opening polymerization (ROP) of L-lactide initiated by two telechelic polyester polyols using an organic catalyst. B blocks were ...
Organic-Acid Mediated Bulk Polymerization of e-Caprolactam and Its Copolymerization with e-Caprolactone
(Wiley, 2016-03-09)
Polyamides (PA) constitute one of the most important
classes of polymeric materials and have gained strong
position in different areas, such as textiles, fibers, and construction
materials. Whereas most PA are synthesized ...
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 ...
