Disulfonated poly(arylene ether sulfone) random copolymers with controlled oligomeric mol. weights were synthesized via nucleophilic aromatic substitution step polymerization A monofunctional endcapping reagent, meta-aminophenol, was utilized to control the mol. weight of the oligomers and to install telechelic amine endgroups. The meta-aminophenol end-capped oligomers were reacted with acryloyl chloride to obtain novel crosslinkable poly(arylene ether sulfone) oligomers with acrylamide groups on both ends. The chem. compositions of the functional oligomers were characterized by 1H NMR spectroscopy to determine the degree of sulfonation and concentrations of acrylamide endgroups. The acrylamide-terminated oligomers were crosslinked with UV radiation in the presence of a multifunctional acrylate and a UV photoinitiator. Transparent, free-standing, dense films were obtained with high gel fractions. FTIR spectroscopy was utilized to observe the progress of the photo-crosslinking reaction. Thin films were cast from either aqueous or water-methanol solutions The crosslinked disulfonated poly(arylene ether sulfone) networks exhibited reduced water uptake and swelling relative to their linear counterparts. SEM and AFM showed that the photo-crosslinked thin films had smooth surfaces. In the experiment, the researchers used many compounds, for example, Diethyleneglycoldiacrylate (cas: 4074-88-8SDS of cas: 4074-88-8).
Diethyleneglycoldiacrylate (cas: 4074-88-8) belongs to alcohols. Alcohols are among the most common organic compounds. They are used as sweeteners and in making perfumes, are valuable intermediates in the synthesis of other compounds, and are among the most abundantly produced organic chemicals in industry. The most common reactions of alcohols can be classified as oxidation, dehydration, substitution, esterification, and reactions of alkoxides.SDS of cas: 4074-88-8
