Examples of materials which are not polymers include:
Elements
.
Metals
.
Ionic compounds, such as salt
.
Which of the following are examples of polymers?
Examples of synthetic polymers include
nylon, polyethylene, polyester, Teflon, and epoxy
. Natural polymers occur in nature and can be extracted. They are often water-based. Examples of naturally occurring polymers are silk, wool, DNA, cellulose and proteins.
Which of the following is not an example of polymer?
Terylene (or dacron)
is not an example of addition polymer
What is non polymer?
Natural non-polymer inorganic macromolecular compounds can be
native metals
, like gold and mercury, or metal ores (L2). The basic organic polymers, biopolymers with very complicated and complex forms and structures, are proteins, nucleic acids, and polysac- charides.
Which of the following is not an example of a polymer 2 points?
The answer is:
sucrose
.
What is a polymer simple definition?
polymer,
any of a class of natural or synthetic substances composed of very large molecules
, called macromolecules, that are multiples of simpler chemical units called monomers. … Polymers are not restricted to monomers of the same chemical composition or molecular weight and structure.
Is cotton a polymer?
Cotton is a polymer which is
made up of cellulose
. Cellulose is a carbohydrate which is also a polymer of repeated chains of glucose. Therefore, the correct answer is option (B). Cotton is a polymer made up of Cellulose.
What are the 3 main types of polymers?
There are 3 principal classes of polymers –
thermoplastics, thermosets, and elastomers
. Differentiation between these classes is best defined by their behaviour under applied heat. Thermoplastic polymers can be either amorphous or crystalline. They behave in a relatively ductile manner but often have low strength.
What are 4 types of polymers?
Terms. Synthetic polymers are human-made polymers. From the utility point of view, they can be classified into four main categories:
thermoplastics, thermosets, elastomers, and synthetic fibers
.
Which is the best definition of polymer?
A polymer is a very large, chain-like molecule made up of monomers, which are small molecules. It can be naturally occurring or synthetic. … Since poly- means “many,” a polymer
means “many parts
.” You’ll find polymers everywhere: they’re what make spandex stretch and sneakers bounce.
What are two types of polymers?
Polymers are of two types:
naturally occurring and synthetic or man made
.
Is PVC a polymer?
Polyvinyl Chloride (PVC) is one of the
most widely used polymers
in the world. Due to its versatile nature, PVC is used extensively across a broad range of industrial, technical and everyday applications including widespread use in building, transport, packaging, electrical/electronic and healthcare applications.
Is nylon a polymer?
Nylon is
a polyamide polymer
characterized by the presence of amide groups—(CO–NH)—in the main polymer chain. A wide variety of nylon polymers are available but only two have found application in tires: nylon 6,6 and nylon 6. … Nylon 6 is produced from caprolactam by a ring-opening polymerization.
Which of the following is an example of additional polymer?
Addition polymers include
polystyrene, polyethylene, polyacrylates, and methacrylates
. Condensation polymers are formed by the reaction of bi- or polyfunctional molecules, with the elimination of some small molecule (such as water) as a by-product. Examples include polyester, polyamide, polyurethane, and polysiloxane.
Which of the following is a thermosetting polymer?
Now
Bakelite
is a cross linked polymer which after heating can not be recovered in its original structure. Hence it is a thermosetting polymer.
What is polymer and its types?
