| abstract | The present invention relates to a siloxane unit of formula R 1 SiO 3/2 , a siloxane unit of formula R 2 SiO 3/2 , and a formula (R 3 O) b SiO (4-b) / 2 (wherein R 1 is independently Is selected from the group consisting of alkyl groups having 1 to 5 carbon atoms, hydrogen and mixtures thereof, and R 2 is independently selected from the group consisting of monovalent organic groups having 6 to 30 carbon atoms and substituted monovalent organic groups having 6 to 30 carbon atoms and, R 3 is independently selected from the group consisting of a substituted branched alkyl having 3 to 30 branched alkyl group and having from 3 to 30, b has the formula R 1, contains siloxane units of 1 to 3) 2.5 to 85 molar parts of the siloxane units of SiO 3/2, siloxane units of the formula R 2 SiO 3/2 2.5 to 50 molar parts, and the general formula (R 3 O) b SiO ( 4-b) / 2 siloxane units To a siloxane resin composition comprising an amount of from 5 to 95 molar parts. The siloxane resins are useful for the preparation of insoluble porous resins and insoluble porous coatings. The substrate coated with the siloxane resin is heated to a temperature sufficient to remove the R 2 and R 3 O groups to form an insoluble porous coating having a porosity of 1 to 60% by volume and a dielectric constant of 1.5 to 3.0. |
