Abstract
The adamantane derivatives of the present invention which are represented by the general formula (1):wherein X is a hydrogen atom, alkyl, halogen-containing alkyl, halogen, or hydroxyl-, halogen-, nitrile- or ether-containing hydrocarbyl, and a plurality of X groups, if any, may be the same or different from each other; n1 is an integer of 1 to 14; R1 to R4 may be the same or different from each other and are independently alkyl or halogen-containing alkyl; and Y1 and Y2 may be the same or different from each other and are independently a hydrogen atom or a group represented by the general formula (2):wherein R5 to R7 may be the same or different from each other and are independently a hydrogen atom, alkyl, halogen or halogen-containing alkyl, are excellent in optical properties, heat resistance and acid-dissociating property, and useful as crosslinking-type resins, optical materials such as optical fibers, light wave guides, optical disk substrates and photoresists as well as raw materials thereof, intermediate products of medicines or agricultural chemicals, and various other industrial products.
