Notes

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 the same functionality. Where the chain-ends of the polymer are not of the same functionality they are termed di-end-functional polymers.

All polymers resulting from living polymerization are end-functional but may not necessarily be telechelic.

To prepare polymers by step-growth polymerization, telechelic polymers like polymeric diols and epoxy prepolymers can be used. The main examples are:

Polyether diols;

Polyester diols;

Polycarbonate diols: Polyhexamethylene carbonate diol (PHMCD);

Polyalcadiene diols: Hydroxyl-terminated polybutadiene (PBHT)...

Other examples of telechelic polymers are the halato-telechelic polymers or halatopolymers[4]. The end-groups of these polymers are ionic or ionizable like carboxylate or quaternary ammonium groups.

In this day of overworked technical people, keeping up is nearly impossible.  Maro's mission is to help keep up in as little time as possible.  Bookmark this page and check it often.  You will be surprised what can be picked up in just a few moments spent each day.

These pages list the links as they are found.  Some will abstracted and added to Maro Topics. (RDC 2/7/2012)
