Polyesters are important plastics, with monomers linked by ester moieties. Phosphoesters form the backbone of DNA molecules. 2495-37-6, formula is C11H12O2, Name is Benzyl methacrylate.Nitrate esters, such as nitroglycerin, are known for their explosive properties. Quality Control of 2495-37-6.
Hirano, Tomohiro;Kamiike, Ryota;Yuki, Takumi;Matsumoto, Daishi;Ute, Koichi research published 《 Determination of monomer reactivity ratios from a single sample using multivariate analysis of the 1H NMR spectra of poly[(methyl methacrylate)-co-(benzyl methacrylate)]》, the research content is summarized as follows. Copolymers of Me methacrylate (MMA) and benzyl methacrylate (BnMA) were prepared by conventional radical copolymerization in toluene at 70°C. The 1H NMR (NMR) spectra of these copolymers were measured in various solvents at different temperatures The signals of the methoxy protons in the MMA units and the benzyl protons in the BnMA units showed splitting mainly because of the triad monomer sequences when the temperature was increased to 150°C in deuterated DMSO. However, the splitting was not sufficient to determine the molar ratios of the triad sequences. Therefore, multivariate anal. was applied to the 1H NMR spectra of copolymers with various chem. compositions Principal component anal. successfully extracted information on the polymer microstructures. Partial least-squares (PLS) regression successfully predicted the mole fractions of the diad monomer sequences. Then, the fractions of the diad sequences in an unknown sample prepared in benzene at 60°C were predicted using PLS regression to determine the monomer reactivity ratios. Thus, the monomer reactivity ratios were successfully determined from a single sample using multivariate anal. of the 1H NMR spectra of copolymers of MMA and BnMA.
Quality Control of 2495-37-6, Benzyl methacrylate, also known as Benzyl methacrylate, is a useful research compound. Its molecular formula is C11H12O2 and its molecular weight is 176.21 g/mol. The purity is usually 95%.
Benzyl methacrylate is a chemical compound that belongs to the group of benzyl compounds. It has a copolymer structure with methyl ethyl methacrylate (MEMA) and hydroxyl groups. Benzyl methacrylate is produced by polymerization of benzyl chloride with allyl carbonate in the presence of radiation, forming a polymeric matrix. The morphology of this copolymer depends on the length of the benzyl chains and the concentration of MEMA., 2495-37-6.
