DEFINITION

Classification: 521/69

Latex, dispersion, or emulsion contains an additional solid polymer-forming system:

(under subclass 65) Subject matter wherein, in addition to at least one solid polymer initially present in the aqueous latex, emulsion, or dispersion, there is also present a reactant or reactants which under the condition of the reaction and in the absence of the initial polymer would form an additional solid polymer.

50, the (9) Note therein, for a discussion of the terms "two solid polymers or polymer forming system". Reactants which form or are known to form initial solid polymers are included herein as being an additional solid polymer forming system. (See Class 521, subclass 50 (11) Note therein).

70, for processes of preparing a cellular product from a composition containing two or more previously formed solid polymers.
