Dispersionless surface polaritons at twist boundaries of transparent uniaxial crystals are investigated. Exact analytical expressions for the central angles of the sectors of propagation of the surface polaritons are derived for arbitrary degrees of crystalline anisotropy η = ε_‖/ε_⊥ − 1. The character of the change in the propagation sectors is determined with due regard for the isotropic transition layer between the crystals.
