Formation of a fiber from high-molecular-weight plasticized polycaprolactam and study of its properties was written by Poludennaya, V. M.;Zhigotskii, A. G.;Razina, V. Yu.;Bychkovskii, N. I.;Genina, M. A.;Konkin, A. A.. And the article was included in Khimicheskie Volokna in 1970.COA of Formula: C9H13NO2S This article mentions the following:
High-mol.-weight polycaprolactam (I) plasticized with 2-5% N-isopropylbenzenesulfonamide (II) or N-cyclohexyl-m-diethylbenzenesulfonamide exhibited superior physicomech. properties and optimum orientation. Fiber from plasticized I was formed at low temperatures and pressures. For example, I containing 5% II could be spun at 245° compared with 265° for I without II. Spinning pressures were 4 and 12 kg/mm2, resp. In the experiment, the researchers used many compounds, for example, N-Isopropylbenzenesulfonamide (cas: 5339-69-5COA of Formula: C9H13NO2S).
N-Isopropylbenzenesulfonamide (cas: 5339-69-5) belongs to amides. Amides can be viewed as a derivative of a carboxylic acid RC(=O)OH with the hydroxyl group –OH replaced by an amine group −NR′R″; or, equivalently, an acyl (alkanoyl) group RC(=O)− joined to an amine group. Amides can be freed from solvent or water by drying below their melting points. These purifications can also be used for sulfonamides and acid hydrazides.COA of Formula: C9H13NO2S
