Crosslinking is the process by which adjacent chains in a polymer are joined together, forming a network of interconnected chains. This crosslinking enhances the strength and durability of the polymer by reducing flexibility and increasing resistance to breakage.
The bond between the polymer chains can be stretched without breaking, thus the polymer can regain shape after distortion from an outside force: it is elastic.
The term "semitelechelic" in reference to polymers may be a bit misleading. A telechelic polymer is one that has a reactive functional group. Most polymers have reactive groups on a least one end. These are monotelechelic. Linear polymers with reactive groups on both ends are ditelechelic. Branched or star-shaped polymers may be tri-, tetra-, penta-, et cetera telechelic. As I understand the nomenclature (professionally, I am a scientist working with polyethylene glycol), "semitelechelic polymer" is usually used to refer to a monotelechelic polymer.
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.
A collection of monomers is more disordered than polymers. More linked subunits in varied arrangements allows for more random movement, bond formations, and thus energy release. The entropy of a group of monomers is greater than a polymer of the same size.

Yes, Gak is a polymer. It is a type of slime that is made by crosslinking polyvinyl acetate molecules with borax to create a stretchy and gooey material.
Hydrogels are made by crosslinking water-soluble polymer chains to create a three-dimensional network that can absorb water. This crosslinking can be achieved through physical or chemical methods. Physical methods include temperature changes or radiation, while chemical methods involve the use of crosslinking agents such as glutaraldehyde or ethylene glycol dimethacrylate.
This protein crosslinking consists of between primary amine (lysine) and sulfhydryl (cysteine) groups of proteinsand other molecules; which are available with different lengths and types of spacer arms.
It affects the properties of a polymer by it being "combine" with sodium borate.
Sodium borate, also known as borax, acts as a crosslinking agent in the interaction between polyvinyl alcohol and other substances. It helps to form strong bonds between the polymer chains of polyvinyl alcohol, increasing its strength and stability. This crosslinking process is important in various applications such as adhesives, coatings, and films.

Borax acts as a crosslinking agent, linking the polymer chains in the glue together to create a more structured and viscous slime. It helps to create a firmer and stretchier slime texture. However, it's important to use borax in moderation as too much can make the slime too stiff or even cause irritation on the skin.
When two or more join together a polymer forms a molecule.
