The continuum version [1] of the Su-Schrieffer-Heeger model [2] may be generalized to include an external bond [3] and/or site dimerization [5] in order to describe the physical properties of non-degenerate ground state and/or diatomic polymers. We have derived the selfconsistent Bloch eigenfunctions and the ground state energy of the soliton and bipolaron lattice solutions for these models to investigate the thermodynamic stability and to calculate the wave number dependent electronic dielectric function ε(q,ω) in random phase approximation. After Kramers-Kronig transformation the loss function and the plasmon dispersion were determined and compared with results of electron energy loss experiments [4].
