Aminocarboranes nido ‐7‐NH 3 + ‐(7‐CB 10 H 12 ) − and closo ‐1‐NH 3 + ‐(CB 11 H 11 ) − 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 Co III 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‐C 2 B 9 H 10 )‐3‐Co III and copolymerized with methyl methacrylate to high‐molecular‐weight statistical copolymers.
