Polymer synthesis, also called polymerization, is
the process by which monomers (small molecules) are covalently bonded to form a (usually long) polymer chain or network
.
What happens in polymer synthesis?
Polymer synthesis occurs
when small molecules are linked together in order to create a larger structure (a macromolecule)
. In other words, the method for making macromolecules from smaller substituents (monomers) is polymer synthesis.
What are the two methods by which polymers are synthesized?
There are two basic types of polymerization,
chain-reaction (or addition) and step-reaction (or condensation) polymerization
.
What is synthetic polymer?
Synthetic polymers are
derived from petroleum oil
, and made by scientists and engineers. Examples of synthetic polymers include nylon, polyethylene, polyester, Teflon, and epoxy. … Vulcanized rubber is a synthetic (man-made) polymer, while pectin is an example of a natural polymer.

What are the 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 do you mean by polymer?
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 make up many of the materials in living organisms, including, for example, proteins, cellulose, and nucleic acids.
What are the two types of polymer?
Polymers are of two types:
naturally occurring and synthetic or man made
.
How is a polymer formed?
A polymer is a large molecule made up of smaller, joined-together molecules called monomers. … Monomers join together to make polymer chains by
forming covalent bonds
—that is, by sharing electrons. Other bonds then hold the groups of chains together to form a polymer material.
Which of the following is an example of thermosetting polymer?
Bakelite
is a thermosetting polymer.
What is polymer with example?
polymer A substance made from long chains of repeating groups of atoms. Manufactured polymers include nylon, polyvinyl chloride (better known as PVC) and many types of plastics. Natural polymers include
rubber, silk and cellulose
(found in plants and used to make paper, for example).
What is polymer and its uses?
Polymers, a large class of materials, consist of many small molecules named monomers that are linked together to form long chains and are used in
a lot of products and goods that we use in daily life
.
What is the most common type of synthetic polymer?
The Low-Density Polyethylene polymer
is the most common kind of synthetic polymer. It is widely used in household products, and it is abbreviated as LDPE. This kind of thermoplastic is usually prepared from the monomer ethylene.
What are the 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 an example of a biological polymer?
Examples of natural polymers are
cellulose, shellac and amber
. Biopolymers such as proteins and nucleic acids play crucial roles in biological processes. … Examples are cellulose, starch, or glycogen. Polypeptides are polymers of amino acids joined together by peptide bonds.
What are some useful polymers?
