Aminocarboranes nido-7-NH3+-(7-CB10H12)- and closo-1-NH3+-(CB11H11)- were copolymerized with α,ω-dihalogenoalkanes to high-molecular-weight alternating copolymers. The nido-compound copolymer was crosslinked by means of sandwiching two open cages with CoIII ion yielding bis(monocarbollide)-cobaltate(III) units as the new type knot points. Metallacarboranes, 1,1′-diaminobis(monocarbollide)nickelate(IV) and two bridged bis(dicarbollide)cobaltates(III) (8,8′-μ-imino- and 8,8′-μ-oxyimino-), have provided hemipolymers of molecular weight up to a few thousands in the same type of copolymerization. A new methacrylic-type monomer was prepared by reaction of glycidyl methacrylate with 8,8′-(μ-imino)-(1,2-C2B9H10)-3-CoIII and copolymerized with methyl methacrylate to high-molecular-weight statistical copolymers.
