Polymerizable higher diamondoid derivatives
Higher diamondoid derivatives capable of taking part in polymerization reactions are disclosed as well as intermediates to these derivatives, polymers formed from these derivatives and methods for preparing the polymers.
1. A method of obtaining a polymer comprising:
i) subjecting a higher diamondoid derivative containing one or two covalently-attached moiety replacing a hydrogen, which moiety is a polymerizable moiety or is converted to a polymerizable moiety, to polymerization conditions thereby forming a polymerization reaction product containing a higher diamondoid containing polymer; and
ii) isolating the polymer from the polymerization reaction product,
wherein the higher diamondoid derivative has the formula:
wherein
D is a higher diamondoid nucleus, and
R 1 , R 2 , R 3 , R 4 , R 5 and R 6 are independently selected from the group consisting of hydrogen and a polymerizable moiety; provided one or two of the R's is a polymerizable moiety.

4. A higher diamondoid polymer comprising, as a recurring unit, a higher diamondoid derivative having one or two derivatizing moieties attached to the higher diamondoid, said derivatizing moiety covalently bonding the higher diamondoid into the polymer through an ester linkage, an amide linkage, or an ether linkage.
