Oligomers, also known as polycondensates, oligomers, or short polymers.

A low molecular substance with the same chemical structure as polyester fibers, existing within the fibers during the spinning process.

The byproduct of the process typically contains 1% to 3% of oligomers in polyester.

Oligomers are polymers composed of fewer repeating units, with a molecular weight that falls between that of small molecules and large polymers.

The term "oligomer" is derived from the Greek prefix "oligo," meaning "some." Most polyester oligomers...
