Polyester, a condensation polymer, can be produced by chainwise,
acid-catalyzed ring openings of cyclic ester (lactone) without expulsion
of small molecules, and also by stepwise polycondensation of
ω-hydroxycarboxylic acid. | [Definition]
A synthetic polymer
made by reacting alcohols with acids,
so that the monomers are linked by the
group –O–CO–. Synthetic fibers such as
Dacron are polyesters. | [Definition]
polyester: A condensation polymerformed by the interaction of polyhydricalcohols and polybasic acids.Linear polyesters are saturated thermoplasticsand linked by dipole–dipole attraction as the carbonylgroups are polarized. They are extensivelyused as fibres (e.g. Terylene).Unsaturated polyesters readilycopolymerize to give thermosettingproducts. They are used in the manufactureof glass-fibre products. |
