Fluoropolyether-containing polymer-modified silane
A fluoropolyether-containing polymer-modified silane having a hydroxyl group protected with a carbonyl, sulfonyl or phosphoryl group may be synthesized without forming by-products.
BIODEGRADABLE HYBRID POLYMERS USABLE IN MEDICAL TECHNOLOGY OR IN BIOLOGY, STARTING SILANES THEREFOR, AND PREPARATION PROCESS THEREFOR AND USES THEREOF
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. The invention further relates to an organically modified silica polycondensate formed as a result of hydrolytic condensation of the silane or silane mixture and optionally a subsequent organic polymerization of the organically polymerizable groups, with optional addition of an organic, at least difunctional compound to the silica polycondensate prior to the organic polymerization.
