Abstract
Aminocarboranes nido-7-NH3+-(7-CB10H12)(-) and closo-1-NH3+-(CB11H11)( -) were copolymerized with alpha,omega-dihalogenoalkanes to high-molec ular-weight alternating copolymers. The nido-compound copolymer was cr osslinked by means of sandwiching two open cages with Co-III ion yield ing bis(monocarbollide)-cobaltate(III) units as the new type knot poin ts. Metallacarboranes, 1,1'-diaminobis(monocarbollide)nickelate(IV) an d two bridged bis(dicarbollide)cobaltates(III) (8,8'-mu-imino- and 8,8 '-mu-oxyimino-), have provided hemipolymers of molecular weight up to a few thousands in the same type of copolymerization. A new methacryli c-type monomer was prepared by reaction of glycidyl methacrylate with 8,8'-(mu-imino)-(1,2-C2B9H10)-3-Co-III and copolymerized with methyl m ethacrylate to high-molecular-weight statistical copolymers.
