What is a single repeated molecule in a polymer?
A single repeated molecule in a polymer is known as a monomer. Monomers are small, simple molecules that can chemically bond with one another to form long chains, creating the larger, more complex structure of a polymer. For example, in polyethylene, the monomer is ethylene, which repeats to form the polymeric chain. The properties of the resulting polymer are influenced by the type and arrangement of its monomers.
What is monomer density of a polymer?
Monomer density of a polymer refers to the concentration of monomer units within the polymer structure, typically expressed in terms of moles per unit volume. It gives insight into how densely packed the repeating units are within the polymer, which can influence the material's mechanical and thermal properties. Higher monomer density often correlates with increased rigidity and strength, while lower density may result in more flexible and elastic characteristics. Understanding monomer density is crucial in polymer chemistry for tailoring materials for specific applications.
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.
What is a homo polymer?
a polymer which is obtained by the polmerisation of only one type of monomer is known as a homopolymer eg:teflon, polyetheleyne etc...if it is constituted of more than one type of monomer( simpler units) then the polymer is known as copolymereg:dacron, buna s etc
Difference between homo polymer and co polymer?
1.. co polymer is a polymer made of 2 different monomer and homo polymer is a polymer made of single monomer 2.. ex-nylon-66,Buna-S-Rubber are the example of co polymer ex-pvc,neoprene etc are the example of homopolymer

What is polymerize?
a polymer is a plastic. a monomer is a chain of molecules which are alkenes as they have a double covalent bond in them. This monomer is then heated and the double covalent bonds break and join with others to make a longer chain of molecules. this is a polymer-plastic. to find out the name of a polymer add poly to the name of the monomer e.g. ethene is a monomer and when it is heated it makes polyethene which is a plastic.

What is a large molecule that is formed by more than five monomer or small units?
A polymer.
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.

What makes a monomer different than a monosaccharide?
A monomer is a single unit that can bond with other similar units to form a polymer, while a monosaccharide is a specific type of monomer that is the building block of carbohydrates. Monosaccharides are sugars that can exist independently or combine to form more complex carbohydrates, while monomers can be molecules of various types that join together to create polymers.
How do you use monomer in a sentence?
Polymerization reactions typically involve the combination of monomers to form larger molecules. For example, in the production of plastics, monomers are linked together to create polymer chains that give the material its structure and properties.
How do polymers form?
Polymers are formed when monomer units link together through chemical reactions, usually involving the breaking of double bonds. This process is called polymerization and can be initiated by heat, light, or chemical catalysts. The repeating units in a polymer chain give it its unique properties.
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.
Large molecules that are formed by joining smaller organic molecules together?
These are polymers, which are made by linking monomers together through chemical bonds. This joining process is called polymerization, and it can result in a wide variety of complex and diverse molecules with unique properties and functions.
