  • Publication number: 20240409716
    Abstract: The invention relates to silane-azodicarbonamide mixtures containing 5-95% by weight of azocarbonyl-functionalized silane of formula I based on the total amount of azocarbonyl-functionalized silane of formula I, silane of formula II and azodicarbonamide of formula III, (R1)3-a(R2)aSi—R3—NH—C(O)—N?N—R4 (I), 0-90% by weight of silane of formula II based on the total amount of azocarbonyl-functionalized silane of formula I, silane of formula II and azodicarbonamide compound of formula III, (R1)y(R2)3-y Si—R3—Sx—R3—Si(R1)y(R2)3-y (II) and 1-80% by weight of azodicarbonamide compound of formula III based on the total amount of azocarbonyl-functionalized silane of formula I, silane of formula II and azodicarbonamide compound of formula III, R5—NH—C(O)—N?N—C(O)—NH—R5 (III). The silane-azodicarbonamide mixture is produced by mixing 5-95% by weight of azocarbonyl-functionalized silane of formula I, 0-90% by weight of silane of formula II and 1-80% by weight of azodicarbonamide compound of formula III.

  • Patent number: 11325926
    Abstract: An aqueous, storage-stable and preferably colorless composition containing N-vinylbenzylaminoalkyl-functional siloxanols is derived from a reaction of hydrolysis products and optionally, condensation products of hydrolysis products, of at least one aminoalkyl-functional alkoxysilane or a mixture of aminoalkyl-functional alkoxysilanes with vinylbenzyl halide. The composition contains not less than 1% by weight of N-vinylbenzylaminoalkyl-functional siloxanols and/or salts of the protonated N-vinylbenzylaminoalkyl-functional siloxanols and water, based on the weight of the composition. The composition has a pH of 2 to 3.5. A process can be used for producing this composition.
