摘要

Water-free metal oxide colloids or metal oxide polymers of the formula [M(O)X³X⁴]n (1) in an aprotic, organic solvent or solvent mixture, wherein M is Si, Ge, Sn, Ti, Zr or Hf; and X³ and X⁴ are independently O_1/2, H, alkoxy (—OR), wherein R represents an organo radical having 1-20 C-atoms, alkyl having 1-20 C atoms or aryl having 6-C atoms, wherein the alkyl- or aryl radicals an include one or several other halogen substituents, selected from the group of F, Cl, Br or I; and n is from 10-1.000.000.
