Die meisten der \u00fcblicherweise verwendeten externen Weichmacher sind Ester organische Verbindungen, in der Regel keine chemische Reaktion mit dem Polymer, die Interaktion mit dem Polymer bei erh\u00f6hten Temperaturen und das Polymer ist vor allem die Rolle der Quellung, und dann mit dem Polymer zu einer festen L\u00f6sung zu bilden. Weichmacher werden in der Regel als externe Weichmacher bezeichnet.<\/p>\n<p>Zweitens, das Prinzip der internen Plastifizierung und der externen Plastifizierung<\/p>\n<p>1, das Prinzip der internen Plastifizierung<\/p>\n<p>Plastifizierung ist die Einf\u00fchrung eines Monomers in den Polymerisationsprozess des zweiten Monomers, durch die zweite Monomer-Copolymerisation in der molekularen Struktur des Polymers, die Zerst\u00f6rung der Polymer-Molek\u00fclkette der Grad der Regelm\u00e4\u00dfigkeit, die den Grad der Kristallinit\u00e4t des Polymers reduziert, reduziert die intermolekularen Kr\u00e4fte, die Erh\u00f6hung der Plastizit\u00e4t. Wie die Block-Copolymerisation, Pfropf-Copolymerisation und andere Methoden.<br \/>\nEine andere Art der internen Plastifizierung ist die Einf\u00fchrung von verzweigten Ketten (oder Substituenten oder aufgepfropften Verzweigungen) in die Molek\u00fclkette des Polymers; die verzweigten Ketten k\u00f6nnen die Kraft zwischen den Polymerketten verringern und so die Plastizit\u00e4t der Kunststoffteile erh\u00f6hen.<br \/>\nP-Phenylen-Umwelt-Weichmacher<br \/>\n2, externes Plastifizierungsprinzip<\/p>\n<p>Externe Plastifizierung ist mit Hilfe bestimmter niedermolekularer Substanzen mit Solvatationsf\u00e4higkeit, die in die Harzmolek\u00fcle eingemischt werden und den Abstand zwischen den Molek\u00fclen vergr\u00f6\u00dfern, um die intermolekulare Schwerkraft des Harzes zu verringern, gleichbedeutend mit der Anwendung mechanischer Zwangsmethoden, die im Polymer dispergiert werden m\u00fcssen, um plastifiziert zu werden, und im Allgemeinen reagieren sie nicht mit dem Polymer und werden nicht Teil der Polymerkettensegmente. Das Ergebnis der externen Plastifizierung ist eine Verringerung der intermolekularen Gravitationskraft, die das plastifizierte Harz weich macht und die Verarbeitungstemperatur des Harzes verringert.<\/p>\n<h2><strong>Flammhemmende Weichmacher der gleichen Serie<\/strong><\/h2>\n<table style=\"border-collapse: collapse;
