Definitions
- R and R are any functional group conventionally useful for preparing polymers or any group capable of forming a derivative of a hydrocarbon.
- the compounds are 3,3-derivatives of -1,1-biadamantane and are particularly useful for forming polymers with unusually high melting points and exceptional stability.
- the monomeric acid compound 3,3'-dicarboXy-1,1-biadamantane is particularly useful in forming highly stable polymers.

PUBLISHED APRIL 8, 1969 646,764 ADAMANTANE DERIVATIVES Heinz Fritz Reinhardt, Claymont, DeL, assignor to E. I. du Pont de Nemours and Company, Wilmington, Del., a corporation of Delaware Original application Mar. 14, 1963, Ser. No. 265,062. Divided and this application Feb. 8, 1967. Published Apr. 8, 1969 Class 260514 No Drawing. 37 Pages Specification A new class of chemical compounds having the formula: RA(X) AR' in Which A is a 1,3-adamantylene group (a 1,3-radical of adamantane(tricyclo [3.3.1.1 ]decane)) which has the formula and X, R and R are substituents capable of combining with a tertiary alkyl carbon atoms (i.e., t-butyl radical) to form stable compounds, X being a divalent radical, R and K may be the same or diiferent and may be hydrogen or a monovalent radical, m is an integer equal to 0 or 1, and at least one of R and R has a molecular weight greater than six when m is zero are provided for use in forming various polymers.
In general, R and R are any functional group conventionally useful for preparing polymers or any group capable of forming a derivative of a hydrocarbon.
When m in the above structural formula is zero, the compounds are 3,3-derivatives of -1,1-biadamantane and are particularly useful for forming polymers with unusually high melting points and exceptional stability.
The monomeric acid compound 3,3'-dicarboXy-1,1-biadamantane is particularly useful in forming highly stable polymers.
