Abstract
Synthesis and free‐radical initiated copolymerization of N‐acryl‐N,N′‐di‐tert‐butylurea (A‐DitBuU) with ethylene glycol dimethacrylate (EDMA) are described. The A‐DitBuU monomer was prepared by the condensation of acrylic acid to the N,N′‐di‐tert‐butylcarbodiimide (DitBuC) at room temperature. Copolymers of A‐DitBuU with EDMA of different monomer to monomer ratios in the feed were prepared in the presence of dibenzoyl peroxide (Bz2O2) in butanone at 70°C for 48 h up to a high conversion. The obtained crosslinked copolymers are insoluble in organic solvents. Copolymers thermal decomposition resulted in separation of tert‐butylisocyanate (C4H9NCO) in the temperature range between 180 and 280°C and by the formation of the thermally stable molecularly imprinted copolymers of N‐acryl‐N‐terc‐butylamide (A‐tBuA) with EDMA.
