Polymeric \Pol`y*mer"ic\, a. [Poly- + Gr. ? part.] (Chem.)
Having the same percentage composition (that is, having the
same elements united in the same proportion by weight), but
different molecular weights; -- often used with with; thus,
cyanic acid (CNOH), fulminic acid (C2N2O2H2), and
cyanuric acid (C3N3O3H3), are polymeric with each other.
[1913 Webster]
Note: The figures expressing the number of atoms of each
element in a number of polymeric substances are
respectively multiples and factors of each other, or
have some simple common divisor. The relation may be
merely a numerical one, as in the example given above,
or a chemical one, as in the case of aldehyde,
paraldehyde, and metaldehyde.
