Polymer for use as a toner is produced by the reaction of
specific silane monomers with various organic diols in a
relatively simple condensation method,

These polymers have the general formula:

and can be prepared by several methods all involving the
condensation reaction of substituents on silicon such as
halogen (Cl, Br, I), amine (~N(CH

                          2) or alkoxy (~OC2H5)
with the hydroxyl group of the organic diol, This reaction
can take place either neat or in solvent as desired, proceeds
readily and by proper selection of the silane monomer may
offer no problem of by~product removal or undesirable side
reactions. It is considered possible to introduce tribo-~
control components, reactive sites toward colorants, or
other desirable modifications such as Tq into the system by
proper selection or chemically altering either or both of
the reactants (MW for example) before or after the polymer
synthesis. Since many of these materials are readily
soluble in a variety of common solvents final toner
preparation by spray drying techniques is also feasible.

The following Examples illustrate preparation of toners
from materials within the class disclosed,

EXAMPLE I

To a 100 ml flask containing a stirring bar and equipped
with a magnetic stirrer, heating mantle, water condenser and
drying tube was charged the following: 0,03 mole of bis~
