Any polymer whose monomers are linked together by ester bonds
(organic chemistry) An alkane chain of benzene molecules, RCH2CHphenylR.
A material or fabric made from polyester polymer
a polymer of styrene; a rigid transparent thermoplastic;
‘expanded polystyrene looks like a rigid white foam and is used as packing or insulation’;
Of, or consisting of polyesters
Polystyrene (PS) is a synthetic aromatic hydrocarbon polymer made from the monomer known as styrene. Polystyrene can be solid or foamed.
any of numerous synthetic resins; they are light and strong and weather resistant
a complex ester used for making fibers or resins or plastics or as a plasticizer
any of a large class of synthetic fabrics
a synthetic resin in which the polymer units are linked by ester groups, used chiefly to make synthetic textile fibres.
a fabric made from polyester fibre
‘dresses in printed polyesters’; ‘swimwear in a range of fabrics including polyester and silk’;
Polyester is a category of polymers that contain the ester functional group in every repeat unit of their main chain. As a specific material, it most commonly refers to a type called polyethylene terephthalate (PET).
