Answer:

Thermosets are polymeric materials that are cross-linked through chemical bonds, resulting in a three-dimensional network structure. These bonds are formed through a chemical reaction called curing, which occurs when the thermoset material is heated or exposed to a catalyst. Once cured, thermosets cannot be melted or reshaped without decomposition, making them strong and durable materials.

One reason why thermosets are normally amorphous is due to the cross-linking process. Amorphous materials do not have a long-range ordered structure, meaning that their molecules are randomly arranged rather than being arranged in a repeating pattern. During the curing process, the molecules of the thermoset material become cross-linked in a random, three-dimensional network structure. This random arrangement of molecules leads to an amorphous structure, rather than a crystalline structure with a repeating pattern.

Additionally, the curing process often involves the breakdown of the original polymer chains, leading to the formation of smaller, cross-linked molecules. These smaller molecules are less likely to form a crystalline structure, further contributing to the amorphous nature of thermosets.

Overall, the cross-linking process and the breakdown of original polymer chains in thermosets lead to the formation of a random, three-dimensional network structure, resulting in an amorphous material.

Answer:

Step-by-step explanation:

Thermosetting polymers, or thermosets, are polymers that are resistant to heat and are able to maintain their shape and structure once they have been cured or crosslinked. One of the main characteristics of thermosets is that they are highly crosslinked, which means that the chains of the polymer are linked together by strong chemical bonds. This high degree of crosslinking gives thermosets their unique properties, such as their resistance to heat and their ability to maintain their shape. Because thermosets are highly crosslinked, they are typically amorphous, meaning that they do not have a well-defined crystal structure. This is in contrast to thermoplastics, which are polymers that can be melted and reshaped multiple times.
