Thermal expansivity in the thickness direction for three commercially synthesized and processed polyimide films, PMDA-ODA, BPDA-ODA, and BPDA-PDA, have been measured. The expansivity in the thickness direction is significantly higher than that in the in-plane direction. The observed anisotropy is ex
