Neutral and mixed neutral/anionic polymetallooxanes

Abstract

This invention relates to polymetallooxanes having the moiety: ##STR1## wherein n is 1.5, 2, 3, 4, 5 or 6, M.sup.1 is selected from the group consisting of Si, Ge, Sn, Al, Ga, Ti, Zr, or Hf, R.sup.1 and R.sup.2 are selected from the group consisting of H, OH, C.sub.1-8 alkyl, C.sub.1-6 alkoxy, C.sub.2-8 alkene, C.sub.6-12 aryl, C.sub.1-8 hydroxyalkyl, C.sub.1-8 thioalkyl, C.sub.2-12 alkoxyalkyl, C.sub.4-20 heteroaromatic, C.sub.1-10 alkylsilane, C.sub.1-10 alkylsiloxane or combinations thereof, O' is bonded to M.sup.1, another M.sup.1 atom, M.sup.2 or H, wherein M.sup.2 is a group I or II metal of the Periodic Table, and R.sup.3 is independently selected from the group consisting of (CR.sub.2).sub.y, O'--(CR.sub.2 CR.sub.2).sub.y N(CR.sub.2).sub.y --, --(CR.sub.2 CR.sub.2).sub.y N.sub.R (CR.sub.2).sub.y --, O'--[(CR.sub.2 CR.sub.2).sub.y O].sub.y --(CR.sub.2).sub.y, C.sub.1-8 alkyl, C.sub.1-6 alkoxy, C.sub.2-8 alkene, C.sub.6-12 aryl, C.sub.1-8 hydroxyalkyl, C.sub.1-8 thioalkyl, C.sub.2-12 alkoxyalkyl, C.sub.4-20 heteroaromatic, C.sub.1-10 alkylsilane, C.sub.1-10 alkylsiloxane or combinations thereof wherein R is selected from the group consisting of H, OH, C.sub.1-8 alkyl, C.sub.1-6 alkoxy, C.sub.2-8 alkene, C.sub.6-12 aryl, C.sub.1-8 hydroxyalkyl, C.sub.1-8 thioalkyl, C.sub.2-12 alkoxyalkyl, C.sub.4-20 heteroaromatic, C.sub.1-10 alkylsilane, C.sub.1-10 alkylsiloxane or combinations thereof, and wherein y is a number 1 to 10. Also described is a method of producing the claimed polymetallooxanes.
