  • Biodegradable hybrid polymers usable in medical technology or in biology, starting silanes therefor, and preparation process therefor and uses thereof
    Patent number: 10259829
    Abstract: The invention relates to a silane or silane mixture obtainable by reacting a hydrolysable silane of the formula (A): SiR4 in which R is a hydrolytically condensable group or hydroxyl with a compound R*(OH)x where x is 1, 2, 3 or greater 3, where R* has a straight-chain or branched hydrocarbon skeleton which, according to the number x, is monovalent, divalent, trivalent or multivalent, and has a hydrocarbonaceous chain interrupted by at least two —C(O)O— groups, wherein there are a maximum of 8 successive carbon atoms in the individual hydrocarbon units formed by interruptions within this chain and the, or in the case of branched structures at least one, end of the hydrocarbonaceous chain at the opposite end to the sole hydroxyl group or one of the hydroxyl groups bears an organically polymerizable group, wherein the alcohol is otherwise unsubstituted or has further substituents.
