Procedure

Preparation of Styrene Terminated Bisphenol-A-Formaldehyde (STBPA-F). Bisphenol-A-formaldehyde resin was prepared as follows. 150.0 g (0.658 moles) of bisphenol-A was dissolved in 500 ml of ethanol in a 1 liter round bottom flask equipped with condenser and magnetic stirrer. To this reaction mixture was added 0.5 ml of concentrated sulfuric acid. The solution was heated to reflux and then 14.5 g (0.151 moles) of paraformaldehyde was added gradually to the reaction. The reaction was heated at reflux with stirring for 48 hours and then allowed to cool to room temperature. The reaction was neutralized with aqueous sodium hydroxide solution and then concentrated under vacuum, yielding 130.3 g of viscous syrup, with a Mw =362.
