In this work, we synthesized polyimides by incorporating an aromatic diamine monomer with a methylene linker, 4,4'-methylenebis(2,6-dimethylaniline) (MBDMA), along with aliphatic
polyetherdiamine backbone linkers and pyromellitic dianhydride (PMDA) as seen in Fig.
Fourier transforms infrared (FTIR) spectroscopy and curve-fitting methods are helpful to determine the pitch aromaticity and identify functional groups and aliphatic
and aromatic hydrogens [18-24].
This paper discusses details of thin-film aliphatic
polyureas including different chemistries and process parameters.
Fulvic acid is lower molecular weight macromolecule, soluble at all pH values, mixture of yellow to brown color, These molecules are known to be heterogeneous polyacids with polymeric structure formed by different types of functional groups like aliphatic
and aromatic organic acids having many aromatic rings attached to (carboxyl, phenols, quinones and semiquinones) [5,8,9,12] and the number of oxygen containing functional groups is more than humic acid .
*Where resistance to acids, aliphatic
& aromatic hydrocarbons, fuels, and ozone is required.
According to Eugenie Charriere, the aliphatic
isocyanates marketing and sales director for Europe, Middle East & Africa, Vencorex has long-term strategic ambitions that include enhancing its commercial presence in Eastern Europe.
Significant efforts have been directed towards the catalytic alternating copolymerization of aliphatic
epoxides with carbon dioxide that generates aliphatic
polycarbonates with a wide array of applications.
5 Adhesive Myth: Aliphatic
resins are better adhesives than regular PVA's.
These include Quadrathane polycarbonate-based TPUs (aromatic and aliphatic
), Quadraflex polyether TPUs (aromatic and aliphatic
), and Quadraplast rigid aromatic grades.
The variable aliphatic
chain length between the two carboxylic acid groups results in the ability to achieve an assortment of physical properties.
The company's integrated aliphatic
thermoplastic polyurethane (TPU) range of solutions features the latest developments and improvements in Merquinsa legacy aliphatic
TPUs for molding.
It is comprised of a surfactant system (including an alkox-ylated nonionic surfactant, a sulphated or sulphonated anionic surfactant; and a neutralizing co-surfactant); a thickener or mixture thereof; a chelant or mixture thereof; a solvent selected from the group consisting of ethers having from 4 to 14 carbon atoms, diethers having from 4 to 14 carbon atoms, glycols, alkoxylated glycols, alkoxylated aromatic alcohols, aromatic alcohols, alkoxylated aliphatic
alcohols, C8-C14 alkyl hydrocarbons, C8-C14 cycloalkyl hydrocarbons, C8-C14 alkyl ha lohydrocarbons, C8-C14 cycloalkyl halohydrocarbons, C6-C16 glycol ethers, and mixtures thereof; and water.
aldehydes, such as hexanal, (E)-2-octenal and nonanal, were produced as off-flavors when the samples were in storage.
