StructureAcrylic-melamineThis article reports a study of the influence of UV light irradiation in the presence of oxygen on both the chemical structure evolution and mechanical properties of an acrylic-melamine (AM) thermoset. Photo-oxidation of the thermoset was investigated by several techniques, ...
It was investigated the influence of chemical structure on the linear viscoelastic rheological behavior of polymer blends comprising acrylic and styrenic polymers. Fourier transform infrared spectroscopy revealed a different bands characteristic of the chemical structures of the polymers. The chemical compositio...

Chemical Structure and Synthesis Poly(acrylic acid) (PAA) has a carboxyl group on every two carbon atoms of the main chain. It has high negative charge density when all carboxyl groups dissociate. This polymer and poly(sodium acrylate) (NaPAA) are thus one of the most abundantly used water...
Acrylic acid, also known as prop-2-enoic acid, is an organic molecule with the formula C3H4O2, and is the simplest of the unsaturated carboxylic acids. At room temperature, acrylic acid is a colorless liquid with a tart or acrid smell. Industrially, acrylic acid is produced from the ...
