Ethyleneglycol diacrylate

In this contribution we present results obtained with tetra-ethyleneglycol diacrylate (TEGDA). This compound was chosen since its polymer shows an easily discernible maximum in the mechanical losses as represented by tan 5 or loss modulus E" versus temperature when it is prepared as a thin film on a metallic substrate. When photopolymerized at room temperature it forms a densely crosslinked, glassy polymer, just as required in several applications. Isothermal vitrification implies that the ultimate conversion of the reactive double bonds is restricted by the diffusion-limited character of the polymerization in the final stage of the reaction. Therefore, the ultimate conversion depends strongly on the temperature of the reaction and so does the glass transition.

Several BP biodegradable and non-biodegradable vinylic monomers can be synthesized under laboratory conditions. By tbe dispersion copol5nnerization of three monomers—the cross-linker monomer tetra[ethyleneglycol)diacrylate,N-(3-aminopropyl)methaciylamide, and methacrylate polyethylene glycol (PEG] BP—these particles are prepared. In the synthesis of these nanoparticles, parametric concern plays a major role by undergoing various pol3mierization techniques.
