WebJul 17, 2001 · Cross-linkers are the metals, such as aluminum citrate and chromium. Polymer concentrations range from 100 to 1200 mg/L, normally 400 to 800 mg/L. The ratio of polymer to cross-linkers is 30–60. Sometimes, this type of gel is called a low-concentration cross-linked polymer. WebAboutTranscript. Polymers can exist as both crystalline and amorphous solids. In fact, most polymers are semicrystalline, which means that they contain a mixture of crystalline and amorphous regions. In this video, we'll see different examples of semicrystalline and amorphous polymers and learn how their structures can be represented using ...
