摘要

评估乳液均聚和共聚过程中单体迁移的达姆克勒数的方法扩展到了气态单体的分析。结果表明，气态单体在均聚和共聚过程中的单体迁移限制在很大程度上取决于总压力，这种关系是通过亨利定律来控制水相中与单体气泡平衡的单体浓度。在低压条件下，所研究的大多数单体都表现出单体迁移限制；然而，即使在非常高的压力下，一些气态单体仍然表现出单体迁移限制。

Monomer Transport in Emulsion Polymerization IV Gaseous Monomers

Methods for the evaluation of the Damkohler number for monomer transport during emulsion homopolymerization and copolymerization are extended to the analysis of gaseous monomers. Results indicate that the monomer transport limitation of gaseous monomers in both homo and copolymerization is strongly dependent on overall pressure through Henry's law relationship governing the concentration of monomer in the aqueous phase in equilibrium with monomer bubbles. At low pressures, most monomers studied exhibit monomer transport limitations; however, even at very high pressures, some gaseous monomers still exhibit monomer transport limitations.
