Concept Search - What can I type?
For a concept search, you can enter phrases, sentences, or full paragraphs in English. For example, copy and paste the abstract of a patent application or paragraphs from an article.
Concept search eliminates the need for complex Boolean syntax to inform retrieval. Our Semantic Gist engine uses advanced cognitive semantic analysis to extract the meaning of data. This reduces the chances of missing valuable information, that may result from traditional keyword searching.

TONER OF SIL~NE DIOL POLYMER Proposed Classification R, L. Schank U,S, Cl, 252/62,1
Int, Cl, G03g 9/00
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,
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~ dimethylarninodiphen...
