2000 Jrnl. Physical Chem. A. 104 8505/1 Cluster ions can range in size from simple dimers such as (He)₂⁺ to large polymolecular species such as water hydrates, H₃O⁺(H₂O)₂.

1925 Proc. National Acad. Sci. U.S.A. 11 638 Phenanthrene spread on an aqueous calcium chloride solution gives a typical polymolecular film.

1931 Jrnl. Physical Chem. 35 869 There was no evidence that the layer of adsorbed molecules was of polymolecular thickness.

1972 M. M. Dubinin in F. Ricca Adsorption-desorption Phenomena 4 On the surface of intermediate pores there occurs monomolecular and polymolecular adsorption of vapours.

1996 Langmuir 12 423/1 The extent of adsorption of n-butanol from water onto nonporous carbon decreases with increasing temperature up to monomolecular surface coverage of the alcohol, but the opposite holds true in the polymolecular adsorption regime.

1940 Chem. Abstr. 34 1228 Such compds. of high mol. wt. are also polymolecular and yield polydisperse solns. Since compds. whose mols. are identical with respect to structure and mol. wt...may form in soln. colloidal particles of varying size, polydispersivity is a condition or state whereas polymer homogeneity and polymolecularity are properties of mols.

1970 J. Fock & M. Fried tr. H. Staudinger From Org. Chem. to Macromolecules 116 In order to characterize a polymolecular macromolecular material with accuracy, it is necessary to know its distribution and to determine how many low and high molecular parts it contains.

1976 H.-G. Elias in K. Solc Order in Polymer Solutions 218 Most synthetic polymers are polymolecular, i.e., the unimers possess a distribution of degrees of polymerization.
