Mechanism of plasticization of crystalline polymers was written by Nizhnik, V. V.. And the article was included in Dopovidi Akademii Nauk Ukrains’koi RSR in 1984.Safety of N-Isopropylbenzenesulfonamide This article mentions the following:
Changes in the dimensions of amorphous regions, physicomech. properties, and glass transition and melting temperatures of crystallizing polymers induced by plasticization were analyzed, and a mechanism of structural and mol. plasticization was proposed. The structural plasticization is associated with adsorption of low-mol.-weight plasticizer during crystallization of the polymer and results in lubrication of supermol. structures. It is confined to a narrow range of plasticizer concentration The mol. plasticization is associated with properties of a solution forming in amorphous regions of the polymer. It increases mobility of polymer chains in these regions and covers a wide range of plasticizer concentration In the experiment, the researchers used many compounds, for example, N-Isopropylbenzenesulfonamide (cas: 5339-69-5Safety of N-Isopropylbenzenesulfonamide).
N-Isopropylbenzenesulfonamide (cas: 5339-69-5) belongs to amides. Amides are pervasive in nature and technology. Proteins and important plastics like Nylons, Aramid, Twaron, and Kevlar are polymers whose units are connected by amide groups (polyamides); these linkages are easily formed, confer structural rigidity, and resist hydrolysis. In simple aromatic amides, fragmentation occurs on both sides of the carbonyl group. If a hydrogen is available in N-substituted aromatic amides, it tends to migrate and form an aromatic amine and the loss of a ketene.Safety of N-Isopropylbenzenesulfonamide
