5.4. Renewable Thermoplastic Polyesters: Polyethylene Terephthalate, Polybutylene Terephthalate, Polyethylene Furanoate
We have seen various aliphatic polyesters (Chapter 4.5) resulting from more direct ways. They include polyhydroxyalkanoate, PHB, polyhydroxyvalerate, polyhydroxybutyrate-co-hydroxyvalerate, polyhydroxybutyrate-hexanoate copolymer.
This subchapter deals with other thermoplastic polyesters, partially or totally synthetized from bioblocks.
5.4.1. Bio-Polyethylene Terephthalate
Development of bio-PET results from a marketing determination developed by steps:
• In a first step, fossil components are partially replaced by biomonomers.
• In a second step, fossil components are totally replaced by biomonomers.
• In a third step, PET could ...
