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.
Why does cross-linking a polymer like polyvinyl alcohol or rubber change its properties How would you make a diagram showing the relationships between a monomer a polymer and cross-liked polymer?
Cross-linking a polymer like polyvinyl alcohol or rubber creates covalent bonds between individual polymer chains, which enhances the material's mechanical strength, elasticity, and thermal stability. This process restricts the movement of polymer chains, resulting in a more rigid and durable structure compared to the unlinked form. To illustrate these relationships in a diagram, you could depict a monomer as a single unit, show it joining to form a polymer (a long chain of repeating units), and then represent cross-linking by drawing connections between different polymer chains to highlight the network structure of the cross-linked polymer.
What is the monomer of the polymer silk?
Silk is actually a polymer made by protein complexes in the repeating fashion.
Why does adding more initiators result in shorter polymer chains?
Adding more initiators can result in shorter polymer chains because more initiators will generate more free radicals, which will initiate more polymerization reactions in the monomer solution. This leads to a higher number of growing polymer chains in the same volume, each receiving less monomer incorporation, thus resulting in shorter chains overall.
Does polymer chain length matter?
Yes, polymer chain length does matter as it influences the physical properties of the polymer such as its strength, flexibility, and viscosity. Longer polymer chains generally result in stronger and more rigid materials, while shorter chains may be more flexible and have lower viscosity. The molecular weight of a polymer is directly related to its chain length.
What does a plasticiser allow polymer chains to do?
a plasticiser allows polymer chains to slide over each other more easily :)
What is cross-linked?
covalent bonds between chains of molecules of a polymer or polymers, fastening the chains together. See also cross-linked polymer, under polymer.
The polymer in some sticky plasters is switched off by light because light makes bonds form between the polymer chains suggest why this may make the polymer less sticky?
The polymer must form bonds with the object if it is to stick to it. If the number of bonds between the polymer chains increases, the number of bonds they share with other objects will probably decrease, making it less sticky.

Polymer made up of chains of amino acids?
Polymer made up of chains of amino acids, also called a polypeptide?
What is the significance of the Flory characteristic ratio in polymer science and how does it influence the behavior of polymer chains?
The Flory characteristic ratio is important in polymer science because it helps determine the size and shape of polymer chains. It influences the behavior of polymer chains by affecting their flexibility, stiffness, and ability to interact with other molecules. A higher Flory characteristic ratio indicates a more extended and flexible polymer chain, while a lower ratio indicates a more compact and rigid chain.
What is a small molecule that forms a link in polymer chains?
a monomer
How Monomer And Polymer related?

What are small molecule that form links in polymer chains?
The links in a polymer chain are covalent bonded.
What makes a polymer elastic?
Polymers are elastic due to their long chain structure, which allows them to easily stretch and return to their original shape. The intermolecular forces between polymer chains provide the elasticity by allowing the chains to slide past each other when stretched and then recoil when released. The flexibility of polymer chains and the ability to form temporary bonds contribute to the elastic behavior of polymers.
