ABSTRACT:
An optically transparent organometallic polymer is disclosed prepared from a polyvalent metal salt-containing monomer of the formula ##STR1## wherein M is a polyvalent metal, R is C.sub.1 to C.sub.12 alkyl, R.sub.1 is C.sub.1 to C.sub.12 alkyl, phenyl or naphthyl unsubstituted or substituted with C.sub.1 to C.sub.6 alkyl, C.sub.1 to C.sub.6 alkoxy, amino, C.sub.1 to C.sub.4 alkylamino, di-C.sub.1 to C.sub.4 alkylamino, nitro or halo or heterocyclic aryl, the heteroatom selected from the group nitrogen, oxygen and sulfur. A process for preparing these high metal content optically transparent materials is disclosed. The polymers are useful in forming transparent radiation barrier sheets and films.
