Effect of heating, plasticizing, and filling on spherulite size distribution, and physical and mechanical properties of crystallizable polymers was written by Pelishenko, S. S.;Solomko, V. P.. And the article was included in Vysokomolekulyarnye Soedineniya, Seriya A in 1971.Formula: C9H13NO2S This article mentions the following:
Plasticization of crystallizing polyformaldehyde (I) (of mol. weight 60,000) with small amounts of Ph2NH and castor oil and of polycaprolactam (II) (of mol. weight 28,000) with N-isopropylbenzenesulfonamide and filling with kaolin and Aerosil led to improved physicomech. properties and spherulite size distribution. Addition of large amounts of plasticizers had the opposite effect. The flexural strength and impact strength of I increased following heat treatment at 160°. The spherulite size of I and II increased as the heat treatment temperature was raised from 140 to 160°. In the experiment, the researchers used many compounds, for example, N-Isopropylbenzenesulfonamide (cas: 5339-69-5Formula: C9H13NO2S).
N-Isopropylbenzenesulfonamide (cas: 5339-69-5) belongs to amides. In primary and secondary amides, the presence of N–H dipoles allows amides to function as H-bond donors as well. Thus amides can participate in hydrogen bonding with water and other protic solvents; the oxygen atom can accept hydrogen bonds from water and the N–H hydrogen atoms can donate H-bonds. Ionic, or saltlike, amides are strongly alkaline compounds ordinarily made by treating ammonia, an amine, or a covalent amide with a reactive metal such as sodium.Formula: C9H13NO2S
