Abstract: The present invention generally relates to compositions including linear cycloaliphatic siloxane polymers, and the cyclic cycloaliphatic siloxane oligomers from which they are made. The present invention also generally relates to methods for making cycloaliphatic siloxane polymers, and the cyclic cycloaliphatic siloxane oligomers from which they are made. Some embodiments relate to cationic polymerization of methyl, cyclopentyl, and/or cyclohexyl substituted polysiloxanes. In some embodiments the cationic polymerization is a cationic ring-opening polymerization.

Abstract: A curable composition having an epoxy component and an organosilane component. The epoxy component includes at least one epoxy compound having two or more epoxide functional groups. The organosilane component includes at least one organosilane compound having two or more silyl ether groups. An exemplary organosilane compound is a siloxane-modified polyol.

Abstract: A ceramer precursor coating composition capable of being formed into ceramer coatings having high tensile modulus and tensile strength while retaining a relatively low strain-at-break are provided. The ceramer precursor coating composition includes unsaturated oil stock and sol-gel precursor. The sol-gel precursor includes a mixture of at least two sol-gel precursor species which are based on different metal atoms. An article having at least one surface coated with a ceramer coating formed from the inorganic/organic coating composition is also provided.
