INCLUSION COMPOUND FORMED BETWEEN POLY(EPSILON-CAPROLACTONE) AND UREA

Molecular modeling of aliphatic polyesters and polyamides suggested that both classes of polymers may be capable of forming these IC's. For example, it was suggested that poly(Ε-caprolactone)(PEC) chains in either the all-trans or kink conformations are slim enough to fit in these narrow IC channels. Here we report the successful formation of the IC between PEC and U, and our preliminary studies of its stability, stoichiometry, and structure, both the three-dimensional, solid-state structure of the PEC-U-IC and the conformation adopted by the included PEC chains.
