represent a selection. Furthermore, it should be mentioned that the journal ''High
Performance Polymers'' is focused on syntheses and characterization of polymers
having outstanding thermal and mechanical properties.
6.4 Poly(alkylene terephthalate)s
In his papers and patents on aliphatic polyesters Carothers mentioned terephthalic
acid as potential reaction partner of a,x-alkanediols, but a description of a con-
crete experiment or polyester was never published. Therefore, it is correct that
