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 ...
Unexpected structural properties in the saturation region of the odd-even effects in aliphatic polyethers: Influence of crystallization conditions
(ACS, 2022-01-04)
A series of aliphatic polyethers with different chain lengths (nCH2= 6 to 12, and 16) is
studied employing differential scanning calorimetry and X-rays scattering. The
calorimetric and structural behavior of samples ...
Experimental and Data Fitting Guidelines for the Determination of Polymer Crystallization Kinetics
(Springer Nature, 2022-05-05)
The crystallization kinetics of semicrystalline polymers is often studied with isothermal experiments and analyzed by fitting the data with analytical expressions of the Avrami and Lauritzen and Hoffman (LH) theories. To ...
Peculiar self-nucleation behavior of a polybutene-1/ethylene random copolymer
(Wiley, 2021-07-31)
The self-nucleation behavior of a polybutene-1/ethylene random copolymer, P(B1-ran-E), which undergoes a complex crystal-crystal transition behavior, has been studied in detail. Similar to PE random copolymers, this material ...
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 ...
2D and 3D Immobilization of Carbon Nanomaterials into PEDOT via Electropolymerization of a Functional Bis-EDOT Monomer
(MDPI, 2021-01-29)
Carbon nanomaterials (CNMs) and conjugated polymers (CPs) are actively investigated in applications such as optics, catalysis, solar cells, and tissue engineering. Generally, CNMs are implemented in devices where the ...
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, ...
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 ...
