Low‐Molecular‐Weight Poly(α‐methyl β,L‐malate) of Microbial Origin: Synthesis and Crystallization

Zusammenfassung

Low-molecular-weightpoly(alpha-methyl beta,L-malate) made of approximately 25-30 units was prepared from microbial poly(beta,L-malic acid) by treatment with diazomethane. The thermal characterization of the polymalate methyl ester was carried out and its crystalline structure was preliminary examined. Its ability to crystallize both from solution and from the melt was comparatively evaluated.
