- 13. The composition of matter of claim 1, wherein said extender is present in an amount ranging from about 1% to about 25% by weight of said composition.
- 14. The composition of matter of claim 13, wherein said extender is present in an amount ranging from abut 1% to about 10% by weight of said composition.
- 15. The composition of matter of claim 14, wherein said extender is present in an amount ranging from about 1% to about 3% by weight of said composition.
- 16. Analytical apparatus useful in determining an analyte in a sample comprising the composition of matter of claim 1 in the form of a film, and an inert carrier.
- 17. Method for determining an analyte in a sample comprising contacting said sample to the composition of matter of claim 1 and determining formation of a detectable signal formed by reaction of said analyte with said reagent system as an indication of said analyte.
- 18. Method for determining an analyte in a sample comprising contacting said sample to the analytical element of claim 16 and determining formation of a detectable signal formed by reaction of said analyte with said reagent system as an indication of said analyte.
- 19. The composition of matter of claim 1, wherein R.sub.1, R.sub.3 and R.sub.4 are hydrogen and R.sub.2 is phenyl.
- 20. A film-forming composition comprising:
- (i) an aqueous polymer emulsion wherein said polymer is formed of at least one monomer selected from the group consisting of ##STR5## wherein R.sub.1, R.sub.3 and R.sub.4, are the same or different, and are hydrogen or unsubstituted or substituted C.sub.1 -C.sub.6 alkyl, and R.sub.2 is a substituted or unsubstituted aromatic moiety;
- (ii) a reagent system for determination of an analyte; and
- (iii) an amount of an extender sufficient to reduce tackiness of said emulsion.
- 21. The film-forming composition of claim 20 coated on a substrate.
- 22. A film comprising a dried composition of claim 20.
