Why does Cross-links between polymer chains increase the melting point?
Wiki User
∙ 11y ago
Cross-links usually occur when a polymer molecule is at a larger size. A larger sized molecule is held together by stronger covalent bonds, and henceforth the force between the molecules is stronger. As the force between the molecules gets stronger, more energy is needed to separate them, meaning the melting point increases.

What synthetic polymer gets harder as the number of carbon atoms in the polymer chain increase?
Polyethylene
Will heating a lithium- polymer cell increase its efficiency?
yes
Which synthetic polymer get harder as the number of carbon atoms in the polymer chain increase?
Polyethylene gets harder as the number of carbon atoms increases.
Why is polymer bouncy?
Rubber is especially bouncy because of its wrinkled chains between sparse crosslinks. The crosslinking prevents the material being a liquid. The chains become almost linear when the material is stretched. The restoring force is a statistical phenomenon: There are many more wrinkled conformations than "almost linear" ones. The "need" for many conformations increases with temperature as does the restoring force.
What is the difference between a bio-polymer and a synthetic polymer?
Both the polymers have a repeating structure which is the basic definition of polymer.
What synthetic polymer gets harder as the number of carbon atoms in the polymer chain increase?
Polyethylene
What are the Relationships between polymer and a monomer?
A polymer is build out of its monomers.
