Ethyl methacrylate, chemical structures

We have recently evaluated the ATRP of a wide range of hydrophilic monomers such as 2-sulfatoethyl methacrylate (SEM), sodium 4-vinylbenzoate (NaVBA), sodium methacrylate (NaMAA), 2-(dimethylamino)ethyl methacrylate (DMA), 2-(iV-morpholino)ethyl methacrylate (MEMA), 2-(diethylamino)ethyl methacrylate (DEA), oligo(ethylene glycol) methacrylate (OEGMA), 2-hydroxyethyl methacrylate (HEMA), glycerol monomethacrylate (GMA), 2-methacryl-oyloxyethyl phosphorylcholine (MPC), and a carboxybetaine-based methacrylate [CBMA]. Their chemical structures and literature references (which contain appropriate experimental details) are summarised in Table 1.

The chemical structure of studied polymers is shown in Fig. 2. Three different types of functionalized polymers have been investigated. In the first case (DRGMMA) the copolymer has been got by free radical polymerization of a 1 1 molar ratio mixture of methyl methacrylate and 4 -(N-ethyl-N-(methacryloxyethyl)amino)-4-nitroazobenzene obtained by esterification with methacrylic acid of commercially available Disperse Redttl. It corresponds to... 

In study of ionic exchange membrane, FT-IR method was usually used to analyze the chemical structures of formed membrane. Fang et. al., prepared novel anion exchange membranes based on the copolymer of methyl methacrylate, vinylbenzyl chloride and ethyl acrylate. The structure of membrane was mainly verified by measurement of FT-IR. This study remarkably showed the importance of FT-IR method in analysis of chemical structure of membranes.F I... 

Fig. 5.17 (a) Chemical Structure of Poly (deuterated styrene)-W< cit-2-[2-(2-methoxyethoxy) ethoxy]ethyl methacrylate (dPS-b-PME3MA). (b) Schematic pictures of the conformations of dPS-b-PME3MA in a mixture with PS in air (or in a vacuum) and in water. At the surface in a vacuum or air, the terminal methyl groups of the side chains, circle, cover the stuface. In water, the water-soluble PME3MA blocks are anchored onto the surface of polystyrene and stretching out into water. PME3MA blocks cover the surface in either hydrophobic or hydrophilic environment...

As known, polymethacrylates split off only the corresponding monomers. This is reflected in the thermofractogram of a polymer mixture (see Fig. 26 below). There are, nevertheless, characteristic differences between individuals. n-Butyl- and ethyl-methacrylates appear in the form of a double spindle (zones 2 and 1, respectively) whereas decylmethacrylate occurs as a single spindle form (zone 3). Since free monomers cannot be present in the polymer mixture, this finding demands the assumption of two competing fission mechanisms for poly-n-butyl- and polyethylmethacrylates. The chemical structure of the monomer evidently influences appredably the degradation behaviour of polymethacrylates. 

Comparison of a PS-PMMA blend with a corresponding copolymer gave information on the chemical drift. In the analysis of a competitive modified vinyl polymer sample by SEC/FTIR, some of the components of the binder could be readily identified (vinyl chloride, ethyl methacrylate, acrylonitrile), and an epoxi-dized drying oil additive was also detected. An analysis of styrene-butadiene copolymers, including a determination of the styrene/butadiene ratio and of the micro structure of the butadiene units cis/trans, l,2-/l,4-units), was performed by Pasch et al.
