Patent Summary

U.S. Patent Classes & Classifications Covered in this listing:

Class 525: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 Series  

Part of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing.

Subclass 123: With saturated -N=C=X (X is chalcogen) reactant or polymer thereof; or with solid copolymer derived from at least one -N=C=X reactant wherein at least one of the reactants forming the solid copolymer is saturated; or with SPFI wherein at least one of the necessary ingredients contains a -N=C=X group or with a reaction product thereof; or with SICP containing a -N=C=X group
Subclass 131: Contacting with -N=C=X-containing reactant and with additional organic reactant containing a hydroxyl or amine group or polymer thereof
Subclass 474: Solid polymer derived from silicon-containing reactant

Class 528: Synthetic Resins Or Natural Rubbers -- Part Of The Class 520 Series

Part of the Class 520 Series - some general types of subject matter include: Solid synthetic resins, per se, regardless of utility; processes of preparing a synthetic resin involving a chemical reaction; reactable compositions which form a product; processes of purifying a solid synthetic resin or composition containing a synthetic resin by a chemical or physical process; process of reclaiming or recovering a solid synthetic resin; processes of treating a synthetic resin or specified intermediate condensation product with a reactant, or product thereof; blends of solid synthetic resins, processes of preparing or treating such blends; chemically reacted solid synthetic resins or processes of preparing; potentially reactable compositions which contain a solid synthetic resin or SICP and products of such a reaction, or processes of preparing; room vulcanizable potentially reactive compositions which merely require moisture and which are usually activated by heat and/or pressure to form a product; compositions of a nonreactant material and a solid synthetic resin or SICP; compositions containing a structurally defined material which is dispersed in a matrix which is not identified by overall dimension or some structure or processes of preparing; single-layered products containing a solid synthetic resin or composition thereof reciting no structure or dimension, or a fiber, filament, etc., which is no more than the material from which it is made, nonstructured single-layered web or sheet is encompassed; particles or a powder, per se, of a solid synthetic resin or composition thereof for which particles or powder no dimensions are recited; reactable compositions which form a product proper for this class and contain a photoinitiator or photosensitizer which are activated by wave energy or processes of preparing.

Subclass 35: Silicon reactamt contains only carbon atom, only a carbon chain, or chain of carbon and oxygen atoms only between two silicon atoms
Subclass 38: Silicon reactant contains an amine nitrogen atom
Subclass 43: Silicon reactant contains an aryl group
Subclass 68: With organic compound reactant containing at least two NH, HNH or =NH groups and wherein the reactant composition is devoid of -C-XH, -C(=X)XH or anhydride
Subclass 85: With reactant containing at least two -XH groups
