Nucleation limiting reagent

A, noted as the detection limit by the authors). TPA+ was present in excess in these experiments [56], as in the previous study discussed [25], and it, therefore, was not a limiting reagent. One has the same question in this case, then, of why only a fraction of the TPA" would be expected to participate in nucleation. However, it is worth considering that the proposed structures, proven to exist for the first time by these authors [56], could be participants in zeolite crystal nucleation and growth. 

Nucleation occurs in a single burst, and consiunes a very small amount of the limiting reagent... 

This paper focuses on heterophase free radical polymerizations. It is limited to processes where multiple phases, distinguished by the insolubility of reagents, exists at the onset of the reaction. It therefore does not consider precipitation polymerization [1], which occurs when the polymer is insoluble in the monomer and precipitates out from an initially homogeneous solution. It also does not address emulsifier-free polymerization or dispersion polymerization. This rather general nomenclature is now accepted as applying to specific systems where the heterophase nature is produced at the onset of the reaction by homogeneous nucleation of oligomers or polymer chains which have exceeded their solubility limit [2].
