Versuchsvorschrift

A solution of 4-propargyloxybenzoyl chloride (17.86 grams, 0.092 moles) in 110 milliliters chloroform is added at room temperature over a 2 hour period to a solution of bisphenol A (9.13 grams, 0.040 moles) and triethylamine (15.0 milliliters, 0.018 moles) in 75 milliliters chloroform. After an additional 1.5 hours, the solution is washed with 5 percent aqueous sodium bicarbonate, then with 1N hydrochloric acid. The organic solution is dried and the solvent is removed by evaporation. The product is purified by recrystallization from a 1:1 solution of toluene in heptane. About 21 grams of product are obtained, reflecting a yield of about 96 percent. Nuclear magnetic resonance spectra confirm the identity of the product, and establish its purity. A dynamic scanning calorimetry run shows a melt endotherm at about 144° C. and a polymerization exotherm with a maximum at about 296° C. The heat of polymerization is about 713 joules/gram.
