Title:
NOVEL BISADAMANTANE COMPOUNDS, PROCESS FOR PREPARING THE SAME, AND NOVEL BIADAMANTANE DERIVATIVES
Document Type and Number:
WIPO Patent Application WO/2001/055063
Kind Code:
A1
Abstract:
2-(2-Methyladamantyl)-2'-adamantylmethane compounds of the general formula (I) [wherein Y?1¿ and Y?2¿ may be the same or different from each other and are each hydrogen, halogeno, hydrocarbyl, hydroxyl, hydrocarbyloxy, carboxyl, or hydrocarbyloxycarbonyl], and 3,3'-dialkoxycarbonyl-1,1'-biadamantane derivatives of the general formula (VI) [wherein R is alkyl having 2 to 8 carbon atoms]. The above novel bisadamantane compounds and the above novel biadamantane derivatives are excellent in heat resistance, water resistance and optical properties.
