• diglycidyl ether to give novel oligomeric thermoresponsive epoxide–amine adducts. These oligomers exhibit a lower critical solution temperature (LCST) behavior in water. The solubility properties were influenced with randomly methylated β-cyclodextrin (RAMEB-CD) and the curing properties of the amine–epoxide

Results and Discussion Formation of epoxide-amine adducts Epoxide-amine adducts based on diglycidyl ether of bisphenol A (1) and 4-aminoanisole (3) were synthesized in a MW-assisted one-pot reaction. Thus, 4-nitroanisole (2) was
