What is telomerization?

telometerization is a chemical process that creates a short chain polymers called oligomers, consisting of two to ten recurring units. Oligomers are mixed with polymers of the same type to increase the flexibility and processability of the material. The polymerization reaction is shortened in the polymer reactions of the chain by means of telomerizing process.

The polymerization reactions usually occur relatively quickly. The monomer is the basic unit that forms the spine of the polymer. Monomeric units must usually be coaxial to react either by adding a catalyst or energy. The polymerization reaction takes place almost immediately as soon as the activation energy or the energy obstacle is met to prevent spontaneous reaction.

reaction, even if it proceeds quickly, adds monomers to the string after a second. Polymeric chains continue to grow until the monomer is exhausted. The final molecular weight of the polymer is controlled by how many strings are initiated, the Initial function. Initial conditions wouldThe amount of catalyst, added heat and reactor design.

Polymers, because of their high molecular weight, tend to be stiff. To make the material more conquered, oligomers with a short chain of the same or similar chemical composition are added. Ordinary scents of new cars are caused by migration of oligomers, called plasticizers in this context, from the upholstery of vinyl. The oligomers are short enough to have some volatility, allowing them to detect their nose.

There are many types of polymeric reactions. In the chain transmission reaction, the reactive type of free radical, an unstable molecular species with an unpaired electron that will respond immediately. The steps of the chain propagation of the polymer reaction keep the radical moving along the chain as it grows.

Access to the reactive radical end gains multiple -flows as the chain extends. If the chain transmission reagent is present, the agent will transferFree radical to the new monomer and ends the chain. A free radical monomer begins a new chain. How to end the early string, which is a step of telometerization, and the launch of a new chain work to limit the length of the chain.

string time transfers usually have one weak chemical binding, which facilitates the transmission of unpaired electron. Common agents used are halocarbones, carbons associated with halogen series of elements. Thioles, equivalent of alcohol sulfur with a functional group of sulfur (—SH) are also used.

Short -chain oligomers can undergo telomerization in four configurations: head to head, head to tail, tail to the tail and tail to the head. The oligomer mixture will consist of all four molecules. Polymer chemists study ways to increase predictable telometerization results.
