WebJul 14, 2024 · Glass is the name given to any amorphous (non-crystalline) solid that displays a glass transition near its melting point. This is related to the glass transition temperature, which is the temperature where an amorphous solid becomes soft near its melting point or a liquid becomes brittle near its freezing point . Glass is a type of matter. WebSep 12, 2024 · As a result, many polymers are semi-crystalline, with regions called lamellae where portions of chains have aligned parallel to each other, but also with large amorphous areas that are much more randomly oriented. As a result, a polymer sample might be 80% amorphous with only 20% of its chain lengths aligned in crystalline lamellae.
