ABSTRACT:
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-bwherein R is a group polymerizable photochemically and/or thermally via an organic rest by radical or cationic polymerization; R2is a straight-chain, branched, or cyclic C1-C12alkyl 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)2wherein R1is identical or different and is a straight-chain, branched, or cyclic C1-C12alkyl group or a group polymerizable photochemically and/or thermally via an organic rest by radical or cationic polymerization, provided the group does not contain aryl. The silane resins have dielectric properties useful in extremely high frequency applications.
