Procedure

Using the procedure as described in Example 7-A. 15506.6 grams (16.03 moles) of phenol was reacted wit 831.56 grams (10.26 moles) of formaline, 37% aqueous formaldeyde, using 7.53 grams (0.084 moles) of oxalic acid. The solid product had a Mettler softening point of 90.7° C. The 2-functional content was 15.27 as measured by GPC. The wt. avg. M.w. was 1,098, no. avg. M.W. 714 with a polydispersity of 1.54. The produce contained 15.2% 2-functional components, and a 3-functional component content of 12.67% for a ratio of 2-functional to 3-functional components of 1.2 to 1.0.
