The monomers [2] and [4] have been prepared via enzymatic reactions from commercially available inexpensive starting materials followed by acetylation. This shows, in general, the potential of biotechnology on the development of new polymers, and heat resistant polymers in particular.作者: CRP743 時間: 2025-3-22 02:49
