Claim:
1. A preform for the manufacture by stretch blow molding of a plastic container, preferably a bottle, said preform being of made by injection molding of at least one thermoplastic polymer of at least one FuranDiCarboxylic Acid (FDCA) monomer, preferably 2,5-FuranDiCarboxylic Acid (2,5-FDCA) monomer, and at least one diol monomer, preferably monoethylene glycol (MEG) monomer and said preform comprising: a neck end; a neck support ring; and a closed tubular body portion, the tubular body portion comprising a straight part having a length L′ and a bottom curved part having a radius R; said preform having a ratio Ø/L, wherein Ø is a specific outer diameter of the straight part of the closed tubular body portion and L is a generatrix length of the preform closed tubular body portion, L being such that L=L′=2πR/4, the ratio Ø/L being such that—in an increasing order of preference—: 0.10<Ø/L≦0.50, 0.15<Ø/L≦0.45, 0.20<Ø/L≦0.40, 0.25<Ø/L≦0.35.
