WebDownload a PDF of this page Science of Plastics Definition Plastics are a group of materials, either synthetic or naturally occurring, that may be shaped when soft and then hardened to retain the given shape. Plastics are polymers. A polymer is a substance made of many repeating units. The word polymer comes from two Greek words: poly, meaning many, … WebAziridine is a highly reactive strained ring that allows the synthesis of diverse small molecules. However, few studies have been reported to utilize aziridine to achieve the structural diversity of polymers. Herein, we report an aziridine-based multicomponent polymerization approach toward building-block diversity, and architectural diversity.
