Questions about oligomer-induced discoloration are quite common, severely affecting product quality and causing contamination to equipment, which is difficult to clean. Below is a summary of the questions:

Oligomers, also known as polycondensates, oligopolymers, or short polymers, are low molecular weight substances with the same chemical structure as polyester fibers, found within the fibers themselves. They are by-products of the polyester spinning process. Typically, polyester contains 1% to 3% of oligomers. Oligomers are polymers composed of fewer repeating units, with a relative molecular weight that falls between that of small molecules and high polymers.

The term "oligomer" is derived from the Greek prefix "oligo," meaning "some." Most polyester oligomers are cyclic compounds formed by three ethyl terephthalate units.
