What is a process by which adjacent chains in a polymer joined together and strengthen the polymer?
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.
What will change the properties of a polymer?
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.
What is Semitelechelic polymer?
A semitelechelic polymer is a type of polymer chain that has reactive or functional end-groups on only one end of the chain. This allows for controlled end-functionalization for specific applications, such as attaching molecules or crosslinking agents to one end of the polymer chain.
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.
Which is more disordered a polymer or a collection of monomers?
A polymer is typically more ordered than a collection of monomers because the monomers are more randomly arranged before they are linked together to form the polymer chain. Once the monomers are linked, they become more structured and organized in the polymer.
Is gak a polymer?
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.
How are hydrogels made?
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.
What is protein crosslinking?
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.
What is the importance of crosslinking and chains in polymers?
It affects the properties of a polymer by it being "combine" with sodium borate.

What effect does borax have on slime?
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.

What forms a polymer when two or more join together?
When two or more join together a polymer forms a molecule.
What is thermal cross linking?
Thermal crosslinking is a chemical process in which polymer chains are linked together using heat, resulting in the formation of a network structure. This can enhance the mechanical properties and stability of the material. It is commonly used in industries like plastics, textiles, and rubber to improve the performance of materials.
What describes any polymer that can be stretched more than two hundred percent?
Resorbable polymer
How can you make a flexible polymer more rigid?
At the design stage adding molecules/monomers with more rings than chains will make the polymer more rigid. If this option is not available, adding fiber or particles or fillers is the usual technique. You can make a stiff polymer more flexible by adding plasticizers, but going the other way is more difficult. Technically speaking the polymer itself isn't changing, but the material overall will be more rigid than the polymer matrix due to the fiber support.
