Silane-based resins that can be photochemically and/or thermally structured, single-step method for their production, parent compounds and production methods that can be used for said resins

摘要

A silane resin that can be structured photochemically and/or thermally is obtained by at least partial condensation of a mixture of a) at least one silane compound RaR2bSiX4-a-b wherein R is a group polymerizable photochemically and/or thermally via an organic group by radical or cationic polymerization; R2 is a straight-chain, branched, or cyclic C1-C12 alkyl group; X is identical or different and is a leaving group; a is 1 or 2; b is 0 or 1; a+b is not more than 2; and b) at least one silanediol R12Si(OH)2 wherein R1 is identical or different and is a straight-chain, branched, or cyclic C1-C12 alkyl group or a group polymerizable photochemically and/or thermally via an organic group by radical or cationic polymerization, provided the group does not contain aryl. The silane resins have dielectric properties useful in extremely high frequency applications.
