\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.
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.
