    • Patent AT-E399822-T1: [Translated] SILOXANE RESINS

    Metadata Updated: September 8, 2025

    This invention pertains to a siloxane resin composition comprising RSiO3/2 siloxane units, RSiO3/2 siloxane units and (RO)bSiO(4-b)/2 siloxane units wherein Ris an alkyl group having 1 to 5 carbons, hydrogen, or mixtures thereof; Ris a monovalent organic group having 6 to 30 carbons; Ris a branched alkyl group having 3 to 30 carbons, b is from 1 to 3; and the siloxane resin contains from 2.5 to 85 mole percent RSiO3/2 units, 2.5 to 50 mole percent RSiO3/2 units and 5 to 95 mole percent (RO)bSiO(4-b)/2 units. The siloxane resin is useful to make insoluble porous resin and insoluble porous coatings. Heating a substrate coated with the siloxane resin at a sufficient temperature effects removal of the Rand RO groups to form an insoluble insoluble porous coating having a porosity of 1 to 60 volume percent and a dielectric constant in the range of 1.5 to 3.0.
