Such molecules must be distributed over a range of molecular weights wherein differences in the molecular weight are primarily attributable to differences in the number of monomer units. A polymer comprises the following: a simple weight majority of molecules containing at least three monomer units which are covalently bound to at least one other monomer unit or other reactant; less than a simple weight majority of molecules of the same molecular weight.
