Polyhydroxyimides from resinic acids
Polimery 2000, No 4, 258
SummaryMonomaleimide Diels—Alder adducts of levopimaric acid and diglycidyl ether of bisphenol A (DGEBA), and of levopimaric acid and diglycidyl ether of hydroquinone (DGEH), were prepared and then used to synthesize new polyhydroxyimides in the reaction (Scheme 2) catalyzed by benzyltriethylammonium chloride and carried out in a solvent (NMP) or without a solvent (Tables 1, 2). Chemical, thermal (TG, Table 3), and spectral (IR, 1H NMR) methods were used to characterize the resulting products. The polymer products were found to be thermally stable and soluble in medium and high polarity solvents (Table 4). The solubility appears to have been imparted by pendant OH groups and phenanthrene rings present in the polymer chain.
