What is meant by telechelic polymers?
Definition. Telechelic polymer is a class of reactive polymer possessing reactive functional groups at the chain ends, which are, not from monomers, deliberately introduced for further reactions.
What is the meaning of polymer chemistry?
Polymer chemistry is a sub-discipline of chemistry that focuses on the chemical synthesis, structure, and chemical and physical properties of polymers and macromolecules.

What is a polymer short definition?
A polymer is any of a class of natural or synthetic substances composed of very large molecules, called macromolecules, which are multiples of simpler chemical units called monomers. Polymers make up many of the materials in living organisms and are the basis of many minerals and man-made materials.
What is a polymer easy definition?
: a chemical compound that is made of small molecules that are arranged in a simple repeating structure to form a larger molecule. polymer. noun. poly·mer | \ ˈpäl-ə-mər \
Why are plastic called polymers?
Plastics are considered polymers because, like polymers, plastics are high molecular weight compounds containing several repeating units. These repeating units are the basic molecules called monomers. Polythene contains more than 50000 monomers linked together to form a long chain.
What are the 3 polymers?
From the utility point of view they can be classified into three main categories: thermoplastics, elastomers and synthetic fibers. They are commonly found in a variety of products worldwide. A wide variety of synthetic polymers are available with variations in main chain as well as side chains.
Which is the best description of a telechelic polymer?
A telechelic polymer or oligomer is a prepolymer capable of entering into further polymerization or other reactions through its reactive end-groups.
What is the definition of a Telechelic oligomer?
A telechelic polymer or oligomer is a prepolymer capable of entering into further polymerization or other reactions through its reactive end-groups. It can be used for example to synthesize block copolymers . By definition, a telechelic polymer is a di-end-functional polymer where both ends possess…
How are homo and hetero telechelic polymers obtained?
Telechelic polymers could be obtained by selective transformation of the ω-end-groups, with both homo- or hetero-telechelic species synthesized.
