ABSTRACT:
The present invention relates to a novel oxirane prepolymer comprising the catalyzed reaction product of an inorganic oxide having at least one hydrolyzable oxygen with a difunctional oxirane oligomer having at least one aromatic moiety and at least one oxirane containing aliphatic moiety, characterized in that substantially all of the hydrolyzable oxygen atoms in said oxide are bonded to said oligomer and there is substantially no bonding between oligomer moieties.
The present invention also relates to a novel inorganic oxide containing polymer, said polymer comprising at least three crosslinked prepolymer moieties, each said prepolymer moiety being the reaction product of an inorganic oxide having at least one hydrolyzable oxygen with a difunctional oxirane oligomer having at least one aromatic moiety and at least one oxirane containing aliphatic moiety.
