Photochemical Conversion of Polycyclopropanes

摘要

The esterification of polyvinyl alcohol (PVA) with chloranhydride of phenylcyclopropane acid with the aim of preparation of a different-link polymer containing fragments of the vinyl alcohol and group with cyclopropane ring in the side links has been studied. As a result of the investigation the new polymer has been synthesized, and its composition, structure, and properties on the basis of data of the IR- and NMR-spectroscopy have been determined. The photochemical structuring of the synthesized copolymer has been studied, and it has been established that the modified polymer possesses photosensitivity of the order 48-51 cm~2/J, which allows its use as a negative photoresist.
