Patent Interference No. 103,812
endcapping component. The experiments are described on pages 266 and 268 of Mr. Butler's
notebook no. MV 90-12 and were performed at the direction of Dr. Rosenquist. See RX 15; RR,
pp. 6-7, paragraph 9; RR, p. 21-22, paragraph 7.
Page 266 of notebook no. MV 90-12 describes the first experiment as reacting 57.0 g of
BPA (bis-phenol A), 400 mls of CH2Cl2 (methylene chloride), 325 mls of H2O (water), 0.7 mls
(2 m%) of TEA (triethyl amine), 2.63 gms (3.1 m%) of the "5249-58" product and 30 gms of
COCl2 (phosgene) in a flask. The reaction was run at a pH of 8 for twelve minutes and then
ramped to a pH of 10.2 for the rest of the reaction. See RX 15, RR, pp. 6-7, paragraph 9.
According to Mr. Butler's notebook, the reaction "[r]an good no problem separated quickly.
Washed 2X in 2% HCL and 3X in DI H2O. Dried over MgSO4. Organic phase has slight yellow
color." See the second page of RX 15.
Mr. Butler repeated the experiment twice using 3.48 g (4.1 m%) and 3.9 g (4.6 m%) of
the endcap, respectively. See the second and third pages of RX 15. Page 268 of Mr. Butler's
notebook no. MV 90-12 indicates that the third polymer was submitted for "GPC" and bears the
notation "GPC 21,719." See the third page of RX 15. Pages 266 and 268 of Mr. Butler’s
laboratory notebook no. MV 90-12 are said to have been signed by Carroll Butler and are dated
February 10, 1994. See RR, p. 20, paragraph 5.
According to Dr. Rosenquist, Mr. Butler gave Dr. Rosenquist the polycarbonate polymer
specimens he had produced along with copies of pages 266 and 268 from his notebook. Dr.
