Synthesis of Dipropargyl Esters of Dicarboxylic Acids (Bis-alkyne Monomers).
Then 520.5 mg (1.870 mmol) of dipropargyl sebacate (E8A), a predetermined amount (a variable parameter) of a predetermined catalyst (a variable parameter), and a predetermined ligand (a variable parameter) were added to the reaction solution.
Then the reaction solution was chilled to 0[degrees]C in the ice bath and 6.270 mmol of a dipropargyl ester of dicarboxylic acid, 238.8 mg (1.254 mmol) of catalyst CuI (20 mol%), and 0.874 mL (6.270 mmol) of TEA as a ligand were added to the reaction solution.
Choi prepared OAPS/DPBPA (dipropargyl ether of bisphenol A) nanocomposites with [T.sub.d5] higher than 570[degrees]C [18].
In this work, new modified BMI resins were prepared from OAPS and dipropargyl ether of bisphenol A (DPBPA), and characterized with FTIR, DSC, DMA, TGA techniques.
