0 an artificial material that is a kind of plastic, often used for making clothes, bags, tents, etc.:
1 a polymer (= a chemical substance consisting of large molecules made from many smaller and simpler molecules) in which the polymer units are joined by esters (= substances produced by a reaction between an acid and an alcohol):
Polyesters are another type of condensation polymer.
Polyesters can be made by reacting dicarboxylic acids with diols.
2 a cloth made from artificial substances:
polyester pants
Wearing a garment made of mainly polyester or viscose will make you hot under the collar.
Today polyester fleece is the uniform of hikers, climbers, and backpackers.
Polyesters are polymers whose monomers are bonded to each other via the ester link, COO.
A polyester called PBAT is widely used in agriculture.
As in other polyesters, the multiple repeating units that make up the long, chainlike polyarylate molecules are linked together by ester groups.
Thin fragments of the polyester insulation are visible around the expanding wire.
Polyester patches were sewn in both discs to increase thrombogenicity.
