摘要：

The linearization problem of the bent (banana-like) polycarbonate chain is solved and two linear chains are found that differ in alteration of trans and cis conformations. Calculation of neutron scattering curves from ordered (crystalline-like) regions with linear and bent chains in different arrangements and comparison with experimental scattering curves exclude the existence of linear chains and of crystalline-like ordering in amorphous polycarbonate.
