Thermal characterization of novel p-nitrobenzylacrylate–diisopropyl fumarate copolymer synthesized under microwave energy
Copolymers of p-nitrobenzyl acrylate and diisopropyl fumarate with different feed ratios were synthesized under microwave and thermal heating conditions, and then characterized by IR, ¹H-, and ¹³C-NMR spectroscopy. Average molecular weights were analyzed by size exclusion chromatography (SEC). Monom...
