the teachings of Stamatoff, Watanabe, Kelmchuk, Nakamura, Plischeke and Hachk’s
Chemical Dictionary, she has limited her discussion to Stamatoff, Watanabe, Kelmchuk
and Hachk’s Chemical Dictionary, only. Accordingly, we will do the same.
To that end, we note that Stamatoff discloses synthetic, linear polyamide
compositions which are stabilized by incorporating a copper compound (e.g., copper
acetate), “a halogen compound, and a phosphorus compound from the group consisting of
inorganic phosphorous acids and alkali metal salts thereof; also effective are aryl
phosphites and phosphates, and aralkyl phosphites and phosphates.” Stamatoff, col. 2,
lines 24-28. Kelmchuk discloses synthetic polyamide compositions comprising a
hindered phenolic compound, a copper compound (in the form of a copper salt of an
organic acid; e.g., copper acetate), a metal halide, and a metal hypophosphite. Kelmchuk,
col. 1, lines 1-35. Watanabe discloses polyamide compositions comprising a copper
compound (e.g., copper stearate, copper acetate, and copper halides), and a sulfur-
containing compound (e.g., acid sodium sulphite, sodium thiosulfate, sodium sulfide,
sodium thiocyanate, etc.). Said compositions are said to have improved thermal and color
stability.
After summarizing the teachings of the applied prior art, the examiner states:
Accordingly, the prior art as evinced by Stamatoff’s disclosure relates that
