In the early seventies, Whiteway et al. have criticized Flory for deriving, the MWD function of A_a type polycondensate and proposed a new MWD function themselves.

七十年代初Whiteway等人批评了Flory导出的A_a型缩聚物的分子量分布函数并建议了一个由他们导出的新分布函数。

The adsorption behaviour of chemically different superplasticizers, such as melamine formaldehyde sulphite polycondensate,β-naphthalene sulfonate formaldehyde polycondensate and polycarboxylate, on early hydrating cement phases was studied. For this purpose, pure ettringite AF(subscript t, monosulfate AF(subscript m and syngenite were prepared. The adsorbed amount and zeta potential of early hydration products were measured.
