Participants

Reaction Conditions

Reaction Steps

A mixture of 216 g (0.95 mole) of phenyl neopentyl phosphite, 134 g (0.47 mole) of tetramethyl-bisphenol-A, and 1 g of sodium methoxide were heated together in a round-bottom flask. The temperature of the reaction vessel was raised to 130° C. and a vacuum was applied. Phenol was distilled over a head temperature of 90° C. at 35 mm Hg. The temperature was raised slowly to 160° C. and the vacuum increased to 0.2 mm Hg to remove any phenol and unreacted phenyl neopentyl phosphite. The proton NMR spectrum of the product obtained showed the methyl protons at 0.77, 1.30, 1.60, 2.17 and 2.27 δ (30.8 hydrogens), the methylene protons at 3.37 and 4.43 δ (7.1 hydrogens), and the aromatic protons at 6.83 δ (4.2 hydrogens). This bisphosphite had the following structure: ##STR4##
