Ultrathin membrane of polymethacrylate or polycrotonate and device provided with ultrathin membrane |
| abstract |
ABSTRACT OF THE DISCLOSURE An ultrathin polymeric membrane has a membrane thickness of 10 to 1,000 .ANG.. The membrane is constituted of polycrotonate and obtained by the spin coating method or by the Langmuir-Blodgett method. The polycrotonate contains recurrent units represented by the formula (I) (I) wherein R represents a hydrocarbon group selected from the group consisting of a branched alkyl group having 3 to 12 carbon atoms, a cycloalkyl group having 3 to 12 carbon atoms, a substituted alkyl group having 2 to 6 carbon atoms, a substituted cycloalkyl group having 3 to 10 carbon atoms and a siloxanic hydrocarbon group. |
