What is Semitelechelic polymer?

Answer 1

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.

Answer 2

A semitelechelic polymer is a type of polymer chain that has reactive or functional end-groups on only one end of the chain. This allows for controlled end-functionalization for specific applications, such as attaching molecules or crosslinking agents to one end of the polymer chain.
