Abstract
Abstract A thin film comprising a polymer having linear recurring units wherein an organic group R' is combined alternately with an organic group R 2 through a bivalent bonding group, wherein each of said group R' and said group R 2 has a valence of at least 2 and has at least 2 carbon atoms; each of said linear recurring units having at least one hydrocarbon-containing group R' having 10 to 30 carbon atoms bonded with covalent bond, and a device having the thin film. The thin film of the invention is formed by building-up layers of the above polymer by LB technique, and the obtained film can be subjected to ring closure and to elimination of a known LB compound added as occasion demand by heat treatment to provide a thin film having a thickness of not more than 10,000 A and excellent heat resistance, chemical resistance and mechanical properties, and the device having the thin film is useful particularly as electric and electronic devices.
