What is the meaning of telechelic?

Filters. (organic chemistry) Describing any polymer that has functional groups as its end-groups. adjective.

What is meant by telechelic polymers?

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. Polymers with complex architectures (nonlinear) bearing reactive groups at each of the chain ends are included in this category.

Why does living polymerization occur?

Because living polymers have had their termination ability removed, this means that once your monomer has been consumed, the addition of more monomer will result in the polymer chains continuing to grow until all of the additional monomer is consumed.

What is romp chemistry?

General Information. Ring Opening Metathesis Polymerization (ROMP), a term coined by CalTech chemist Robert Grubbs, is a variant of the olefin metathesis reaction. The reaction uses strained cyclic olefins to produce stereoregular and monodisperse polymers and co-polymers.

What is an example of an oligomer?

For example, oligomers can be nonfunctional, mono functional or multifunctional and be used to enhance performance or environmental properties. Some common oligomer types used in applications in addition to light cure systems include epoxy ester, urethane, epoxy, acrylic, polyester and polycaprolactone.

What are oligomers made of?

IUPAC defines an oligomer as a substance composed of molecules containing a few of one or more species of atoms or groups of atoms (constitutional units) repetitively linked to each other.

What is oligomer in polymer?

Oligomers are low molecular weight polymers comprising a small number of repeat units whose physical properties are significantly dependent on the length of the chain. Oligomers are essentially intermediates of the polymerization reaction that find wide, direct applications in material science.
