Classification of conducting polymers?
polymers are classified into 5 types as follows: A))based on synthesis: 1)addition polymers 2)condensation polymers B))based on inter molecular forces: 1)fibers 2)elastromers 3)thermoplastics 4)thermosettings C))from source 1)natural polymers 2)synthetic polymers D))based on material 1)organic polymer 2)inorganic polymer E))based on structure 1)linear polymer 2)branched polymer 3)cross linked polymer F))based on the monomer 1)homo polymer 2)hetero polymer
What is the difference between a cross linked polymer and a polymer?
A cross-linked polymer is a polymer chain that has been chemically bonded to another polymer chain, creating a network structure. This network structure gives cross-linked polymers unique properties like increased strength, rigidity, and resistance to solvents, compared to linear polymers which have individual chains that are not connected to each other.
What is the significance of polymer crystallization temperature in determining the material properties and performance of polymers?
The polymer crystallization temperature is important because it affects the structure and properties of polymers. When a polymer crystallizes at a higher temperature, it tends to have a more ordered structure, which can lead to improved mechanical strength, stiffness, and thermal stability. On the other hand, polymers that crystallize at lower temperatures may have a more amorphous structure, resulting in lower strength and flexibility. Therefore, the crystallization temperature plays a crucial role in determining the overall performance and properties of polymers.
What are the characteristics of branched polymers and how do they differ from linear polymers?
Branched polymers have side chains branching off from the main polymer chain, giving them a more complex structure. This branching increases their flexibility and reduces their crystallinity compared to linear polymers, which have a straight chain structure. Branched polymers also have lower viscosity and higher elasticity than linear polymers.
Which describes a characteristic of branched polymers?
Branched polymers have side chains connected to the main polymer chain, causing a more complex molecular structure compared to linear polymers. This branching enhances properties such as flexibility, toughness, and viscosity in the polymer material.
What polymer contain nitrogen?
Some common polymers that contain nitrogen in their structure include nylon, protein-based polymers like collagen and keratin, and synthetic polymers like polyacrylonitrile. Nitrogen can be found as part of the backbone or within side groups of these polymers, contributing to their properties and functionalities.
What element forms the backbone of most polymers?
Carbon is the element that forms the backbone of most polymers due to its ability to form strong covalent bonds with other carbon atoms, creating long chains or networks that make up the polymer structure.

What element does polymers rely on for their structure?
Polymers rely on carbon as the main element for their structure. Carbon atoms are linked together in long chains to form the backbone of polymer molecules. Other elements such as hydrogen, oxygen, nitrogen, and occasionally other elements like sulfur or silicon can also be present in polymer structures, but carbon is essential for their formation.
Is Dacron an Addition polymer?
Yes, Dacron is an addition polymer. It is a synthetic polymer produced through the addition polymerization of ethylene glycol and terephthalic acid. This process creates long chains of repeating units, known as polymers, which are characteristic of addition polymerization.
What kind of atom forms the backbone of monomer and a polymer?
The Carbon atom usually forms the backbone of polymers and quite often oxygen can do also as in polyether polyols etc.
Is oxygen the element that forms the backbone of most polymers?
No, carbon is the element that forms the backbone of most polymers. Oxygen may be present in polymer structures as well, but it is the carbon atoms that primarily link together to form the long chains characteristic of polymers.
What do condensation polymers and addition polymers have in common?
Both condensation polymers and addition polymers are formed through polymerization, a process in which monomers are combined to form larger polymer chains. Additionally, both types of polymers can have high molecular weights and are used in a wide variety of applications.
What is the difference between conducting polymer and conjugated polymers?
All the polymer can not be made electrically conductive unless there are sufficient charge carriers available within the polymer itself. These charge carriers are responsible for conduction of electrical current. There is hardly a difference between a conducting polymer and conjugated polymer. The conjugated polymers have alternate single and double bond. Moreover, all conjugated polymers are conducting polymers. Their conductivity is increased on adding a suitable impurity in order to make free charge carriers.
What is the difference between a bio-polymer and a synthetic polymer?
Bio-polymers are derived from renewable resources, such as plants and animals, and are biodegradable, while synthetic polymers are man-made from fossil fuels and are not biodegradable. Bio-polymers have a lower carbon footprint and are more environmentally friendly compared to synthetic polymers.
What is the chemical formula of the polymers rings?
There are lots of polymers, many of which do not contain ring structures. You will need to be more specific as to which polymer you're talking about.One common polymer that does contain rings is polystyrene, in which the rings are simple phenyl rings hanging from a long-chain hydrocarbon backbone. There are also polymers in which the rings are in the backbone, such as poly(ethylene terephthalate) and Kevlar; again, these are phenyl rings in both cases. However, it's certainly possible for there to be rings other than phenyl groups in a polymer.(A phenyl group hanging from the backbone has a formula of C6H5; one that's in the backbone will likely be C6H4, since it needs to connect at two points.)
What is the difference between a cross linked polymer and a polymer?
A cross-linked polymer is a polymer chain that has been chemically bonded to another polymer chain, creating a network structure. This network structure gives cross-linked polymers unique properties like increased strength, rigidity, and resistance to solvents, compared to linear polymers which have individual chains that are not connected to each other.
