The ES nanofibers were annealed at 100 °C for Characterization 1H NMR spectra were obtained at room temperature by using a Bruker AM 300 (300 MHz) spectrometer and d-dimethyl sulfoxide as a deuterated solvent. The molecular weight and molecular weight distribution of poly(HEMA-co- NMA) were ...
The self-diffusion coefficients for water in a series of copolymers of 2-hydroxyethyl methacrylate, HEMA, and tetrahydrofurfuryl methacrylate, THFMA, swollen with water to their equilibrium states have been studied at 310 K using PFG-NMR. The self-diffusion coefficients calculated from the Stejskal-...
Dendritic polyglycerol (PG) was covalently coupled to 2-hydroxyethyl methacrylate (HEMA) by an anionically catalyzed ring-opening polymerization generating... R Wanka,F Koschitzki,V Puzovic,... - 《Acs Applied Materials & Interfaces》 被引量: 0发表: 2021年 Stress growth and relaxation of den...
伪-Methacryloyl-蠅-hydroxyl-poly(-caprolactone) macromonomer was synthesized using stannous 2-ethyl hexanoate (Sn(oct)2) as catalyst and 2-hydroxyethyl methacrylate (HEMA) as initiator. The macromonomer was characterized by SEC, IR and H-NMR. The results confirmed the expected macromonomer ...
(termed PGDO7, Supplementary Fig.30). All of the synthesised POLY-PROTACs displayed controllable polymerisation and narrow molecular weight distributions as determined by1H-NMR and gel permeability chromatography measurements, respectively (Supplementary Table1; all NP compositions and acronyms are ...
In general, most existing hydrogel soft contact lens materials are based on HEMA, also known as hydroxyethylmethacrylate or as ethyleneglycolmonomethacrylate, with one or more optional comonomers as described in U.S. Pat. Nos. 2,976,576, 3,841,985 and 3,985,697. Other hydrogels based on ...
The structures of the synthetic polyurethanes were identified by 1H NMR and FTIR, respectively, as shown in Figures 2 and 3. Figure 2 expounded the 1H NMR spectrogram of BPU performed in CDCl3. As shown in the graph, the resonance peak at 3.869 ppm belonged to the protons of methenyl con...
