La maggior parte dei plastificanti esterni comunemente utilizzati sono composti organici estere, di solito nessuna reazione chimica con il polimero, l'interazione con il polimero a temperature elevate e il polimero \u00e8 principalmente il ruolo di gonfiore, e poi con il polimero per formare una soluzione solida. I plastificanti sono solitamente indicati come plastificanti esterni.<\/p>\n<p>In secondo luogo, il principio della plastificazione interna e della plastificazione esterna<\/p>\n<p>1, il principio della plasticizzazione interna<\/p>\n<p>La plastificazione \u00e8 l'introduzione di un monomero nel processo di polimerizzazione del secondo monomero, a causa della copolimerizzazione del secondo monomero nella struttura molecolare del polimero, distruggendo la catena molecolare del polimero del grado di regolarit\u00e0, che riduce il grado di cristallinit\u00e0 del polimero, riduce le forze intermolecolari, aumentando la plasticit\u00e0. Come la copolimerizzazione a blocchi, la copolimerizzazione a innesto e altri metodi.<br \/>\nUn altro tipo di plastificazione interna \u00e8 l'introduzione di catene ramificate (o sostituenti o rami innestati) nella catena molecolare del polimero; le catene ramificate possono ridurre la forza catena-catena del polimero, aumentando cos\u00ec la plasticit\u00e0 delle parti in plastica.<br \/>\nPlastificanti ambientali a base di P-fenilene<br \/>\n2, principio di plastificazione esterna<\/p>\n<p>La plastificazione esterna avviene con l'aiuto di alcune sostanze a basso contenuto molecolare con capacit\u00e0 di solvatare, mescolate alle molecole della resina, aumentando la distanza tra le molecole al fine di ridurre la forza gravitazionale intermolecolare della resina, equivalente all'uso di metodi meccanici di coercizione, disperse nel polimero da plastificare, e generalmente non reagiscono con il polimero, non diventano parte dei segmenti della catena polimerica. Il risultato della plastificazione esterna \u00e8 una riduzione della forza gravitazionale intermolecolare, che rende la resina plastificata morbida e riduce la temperatura di lavorazione della resina.<\/p>\n<h2><strong>Plastificanti ritardanti di fiamma della stessa serie<\/strong><\/h2>\n<table style=\"border-collapse: collapse;
