Since its commercialization in the 1950’s by DuPont‚ PET was predominantly synthesized out of DMT due to the fact that this monomer‚ compared to TPA‚ was relatively easily purified by distillation. Yet‚ since the 1960’s‚ purified TPA became available by the development of new technologies and gained a lot of importance

The destruction of the apparent extremities implies that day and night are not meant to be extremities as day leads on to night‚ and night leads on to day‚ and thus forms a cycle.
