What will more cross-linking in a polymer?

More cross-linking in a polymer generally increases its mechanical strength, thermal stability, and resistance to solvents. This results in a more rigid and durable material, which can withstand higher temperatures and stress. However, excessive cross-linking can also lead to reduced flexibility and increased brittleness, limiting the polymer's applications. The balance of cross-link density is crucial for tailoring the properties of the polymer for specific uses.
