Abstract
An organometallic polymer having the following moiety: ##STR1## is disclosed. R.sub.1 and R.sub.2 are independently selected from the group of H, alkyl having 30 or fewer carbons, alkenyl having 30 or fewer carbons, and aromatic having one to ten rings; n=0-30; p=0-30; and M is a metal selected from the group consisting of Sn, Ge, Pb, Hg, Ni, Pd, Pt, Cr, Fe, Co, Cu, and Zn. Most preferably, M is Sn, R.sub.1 and R.sub.2 are n-butyl, n is 3, and p is 3. A preferred antibacterial/antifungal composition may be formed by combining the polymer with a suitable carrier.

An organometallic polymer having the following moiety:
- ##STR4## wherein:
- (a) n=0-30;
- (b) p=0-30;
- (c) R.sub.1 and R.sub.2 are independently selected from the group consisting of H, an alkyl group having 30 or fewer carbons, an alkyl group having 30 or fewer carbons, and an aromatic group having one to ten rings;
- and
- (d) M is a metal selected from the group consisting of Sn, Ge, Pb, Hg, Ni, Pd, Pt, Cr, Fe, Co, Cu, and Zn.
A method of making an organometallic polymer comprising the steps of:
- adding a bis(alkyl) metal monomer to a suitable catalyst, but without the presence of a co-catalyst;
- reacting the monomer under vacuum at a temperature between room temperature and 90.degree. C. to form a crude mixture of a polymer having the moiety ##STR5## purifying the polymer from the crude mixture;
- wherein:
- (a) n=0-30;
- (b) p=0-30;
- (c) R.sub.1 and R.sub.2 are independently selected from the group consisting of H, an alkyl group having 30 or fewer carbons, an alkyl group having 30 or fewer carbons, and an aromatic group having one to ten rings;
- and
- (d) M is a metal selected from the group consisting of Sn, Ge, Pb, Hg, Ni, Pd, Pt, Cr, Fe, Co, Cu, and Zn.
