WebJan 6, 2024 · On the other hand, crystallization-induced deracemization is simple to implement and to scale up because of its analogy with cooling crystallization processes (e.g., preferential crystallization). However, its productivity strongly depends on solubility and high product purity can be attained only if it is possible to avoid distomer nucleation. Web(A) Crystallization during polymerization A special attribute of this kind of polymerization is the formation of macroscopic single polymer crystals3(see Figure 2.2 (b)). During such a process the monomers forming a crystal can be joined up into chains by solid state polymerization, while the original “monomer” crystals are preserved.
