DEFINITION

Classification: 523/200

Process of forming a composition of a solid polymer or solid polymer-forming system by admixing a product in the form of a surface coated, impregnated, encapsulated, or surface modified fiber, sheet, particle, or web, with a material; or composition which is the result of said admixing:

(under subclass 1) Subject matter wherein a composition is formed by admixing a material with a product, which product is a surface coated fiber, sheet, particle, or web; or an impregnated fiber, sheet, particle, or web; or an encapsulated or surface modified fiber, sheet, particle, or web; or the composition formed by any of the aforementioned mixing operations.

(1) Note. The product itself as recited above may contain a synthetic resin or material proper for the Class 520 series of classes, e.g., surface coated polymer particle, or the polymer may surface coat another polymer or nonpolymeric material. It is also permissible for this subclass that the polymeric material proper for the Class 520 series be admixed with a product which is a surface coated, impregnated, encapsulated, or surface modified product as noted above but which product itself is devoid of a polymer proper for the Class 520 series.

(2) Note. This subclass requires the admixing of a product proper for this subclass with a material to form a composition wherein at least one ingredient of the composition is nonreactive with a polymer proper for the Class 520 series. The nonreactive material may be the material or the product.

(3) Note. Compositions proper for this subclass either (a) must recite some process language consistent with an admixing process proper for this area, or (b) must be dependent totally or in part on a claim which recites a process proper for this area.

(4) Note. This subclass does not require that the product admixed be in the same physical or chemical state after the completion of the process as when said product was admixed with the material so as to form a composition therewith. For instance, the material may be ground up, further polymerized, transitory, etc.

(5) Note. A solid polymer-forming system is a single reactant or mixture of reactants which are disclosed or claimed as being capable of forming a solid polymer proper

for the Class 520 series under the conditions recited in the claims or which in the absence of a claimed recitation are disclosed in the specification. See the Class 520 class definition for a further elaboration of the type of subject matter proper therein.
