摘要

The term polyester, strictly speaking, refers to a chemical compound containing many ester groups in each molecule. However, in practice it refers to polymeric materials containing ester groups as major structural components of the main chain of the macromolecules of which the polymer is composed and this is the sense in which it is generally used. There has been some confusion in the past with the term alkyd, which is derived from alcohol plus acid. Kienle, in his definition, included all polyesters derived essentially from diols and dicarboxylic acids and consequently, linear polyester was also included. Later, Bjorksten defined the term polyester to the polycondensation products of dicarboxylic acids with dihydroxy alcohols and state that this definition does not include materials commonly known as alkyds. At present, there are still problem of nomenclature in the fibre field arising from the use of polyester as a generic term to cover fibres containing only a very restricted range of chemical group. The term ester applies not only to products derived from carboxylic acids but also to products derived from other types of organic acids such as phosphonic or sulphonic acids and also from inorganic acids.
