FTIR-ATRConoscopy studies have shown that poly(n-butylmethacrylate) (PNBMA) causes LC molecules to align homogeneously (parallel alignment) to the surface while poly(iso-butylmethacrylate) (PIBMA) causes LC molecules to align homeotropically (perpendicular alignment) to the surface. This alignment ...
Three different types of PA membranes were studied, consisting of copolymers of methyl methacrylate with n-butyl acrylate, decyl methacrylate, or isodecyl acrylate. Numerical simulations with the finite difference method showed that in most cases the water uptake of the PA and SR membranes could be...
The silicon-based copolymer solution of methyl methacrylate and butyl acrylate was prepared by one pot, the optimization dosages of the monomers and vinyltriethoxysilane were determined. The solution formed coatings on the surface of glass plate and stone samples. The structure was characterized by FT...
摘要: Gel polymer electrolyte (GPE) has been attractive for developing Li-ion batteries due to its combined advantage of liquid electrolyte (high ionic conductivity) and solid electrolyte (free of leaking). An acrylonitrile(AN)-methyl methacrylate(MMA) copolymer...
Modification of montmorillonite (MMT) through the incorporation of myristyltrimethylammonium bromide (MTAB) into the clay's interlayer spaces were investigated by Small-Angle X-ray Scattering (SAXS), Fourier Transform Infrared Spectroscopy (FTIR), Thermogravimetric Analysis (TGA) and Transmission Electron ...
This technique was later expanded to a series of methacrylate monomers such as methacrylic acid (MAA),338 poly(ethylene glycol) methyl ether methacrylate (MePEGMA),339 ethyl (EMA) and n-butyl methacrylate (nBMA),340 tert-butyl methacrylate (tBMA),341 glycidyl methacrylate (GMA),340 and ...
The structures of the polyester polyols were investigated by 1H–NMR and FTIR. The results show that the the structures of the synthetical products are consistent with the expected structure of polyester polyols. Then the poly(urethane-methacrylate) materials with high temperature resistance were ...
It was also demonstrated from the results of differential scanning calorimetry (DSC) and Fourier transform infrared (FTIR) that the microphase separation of soft and hard phase of PUs in hybrid latexes was more significant than that of original PUs. The PU containing the methacrylic endgroup was ...
甲基丙烯酸甲酯、甲基丙烯酸丁酯、甲基丙烯酸的聚合物 英文名称:2-Propenoic acid, 2-methyl-, polymer with butyl 2-methyl-2-propenoate and methyl 2-methyl-2-propenoate Butyl methacrylate, methyl methacrylate, methacrylic acid polymer 说明:补充资料仅用于学习参考,请勿用于其它任何用途。
The prepared copolymer dispersions were characterized using FTIR, DLS, TGA, DSC and GPC. Additionally, the physical, chemical and mechanical properties of the prepared copolymers were studied. The results showed an increase in the hydroxyl number of CON with increasing transesterification time. Stronger...
