摘要翻译:
提出了一个完全自含的同手性模型,该模型包含了聚合和解离的影响。解离碎片被假定为补充底物,新的单体可以从中生长和进行新的聚合。研究发现,等规聚合物的平均长度随相应构造块的归一化总数而缓慢增长。或者,如果假设解离片段本身可以进一步聚合,那么这对应于短聚合物的强源,并且不切实际地短平均长度仅为3。相比之下,没有解离,全同立构聚合物变得无限长。

英文摘要:
A fully self-contained model of homochirality is presented that contains the effects of both polymerization and dissociation. The dissociation fragments are assumed to replenish the substrate from which new monomers can grow and undergo new polymerization. The mean length of isotactic polymers is found to grow slowly with the normalized total number of corresponding building blocks. Alternatively, if one assumes that the dissociation fragments themselves can polymerize further, then this corresponds to a strong source of short polymers, and an unrealistically short average length of only 3. By contrast, without dissociation, isotactic polymers becomes infinitely long.
