Base-Catalyzed Polymerization of a Substituted Methylenebicyclo[3.3.1]nonane

Figure 2

(a) X-ray diffraction study of lignite humic acid-HCHO/OH^- reaction product which provided evidence for the proposed monomer (poly-(3-amino-1,5-dimethyl-7-methylenebicyclo[3.3.1]nonane-3-carboxylic acid)). (b) ORTEP diagram of BCN polymer obtained from X-ray diffraction studies which again confirms the substituted bicyclo[3.3.1]nonane skeleton.
