What is is the monomer for cellulose?
cellulose is a linear polymer of glucose.
What is polypropylene foam?
Polypropene is a thermoplastic polymer made by the chemical industry packaging, textiles (e.g. ropes, thermal underwear and carpets), stationery, plastic parts and reusable containers of various types, laboratory equipment, loudspeakers, automotive components, and polymer banknotes.
What type of polymer can be described as having only one starting point and one ending point?
A linear polymer, where the monomer units are connected in a straight line, can be described as having one starting point and one ending point. Examples of linear polymers include polyethylene and polypropylene.
What is Semitelechelic polymer?
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.
What happens to each ethene molecule when it becomes polyethene?
Each ethene molecule undergoes a polymerization process where multiple ethene molecules join together to form a long chain polymer known as polyethylene. This polymer has a linear or branched structure depending on the polymerization conditions, resulting in a material with improved strength, flexibility, and chemical resistance compared to individual ethene molecules.
What type of polymer is?
A thermoplastic. A hydrocarbon. A linear hydrocarbon. All of these cklassifications can be applied.
Is Teflon a thermosetting polymer?
No, Teflon is not a thermosetting polymer. It is a thermoplastic polymer. Thermosetting polymers undergo a chemical reaction to form a stable, cross-linked structure when heated, while thermoplastic polymers soften when heated and harden when cooled. Teflon belongs to the latter category.
Model question papers for polymer science?
linear polymer
Describe the formation of polyethene as an example of additional polymerisation of monomer units?
Alkene such as ethene contain c=c double bond.Hence these molecules can take part in addition reaction where the double bond is broken and other atoms attach to the carbon across the double bond to form large molecule such as polyethene. Here the ethene is the monomer and polyethene the addition polymer which is formed under high pressure, heat and by using a catalyst.
Does a linear polymer have to go in a straight line?
Not on the macroscopic scale but microscopically the polymer is a fiber.

What is a block polymer?
A block polymer is a polymer chain consisting of two or more chemically different segments, or blocks, with distinct properties. These blocks can be linked together in a linear, star, or branching configuration. Block polymers are known for their well-defined microstructure and ability to self-assemble into unique nanostructures.
What type of polymer can be described as having only one starting point and one ending point?
A linear polymer, where the monomer units are connected in a straight line, can be described as having one starting point and one ending point. Examples of linear polymers include polyethylene and polypropylene.
What is the material on water pipes?
water pipes are almost always made of a polymer PVC (Poly Vinyl Chloride)... it is a linear polymer with 1-chloro ethene as its repeating unit...
Can you move vectors spirally?
In a fixed frame of reference a spiral vector would be a combination of a linear vector and a rotational vector.In a rotating frame of reference a spiral could be a single linear vector but only to a viewer external to the frame of reference.
