摘要：
Fluorinated oligourethanes, having number average molecular weight lower than or equal to 9,000, having a branched structure, formed of the following monomers and macromers: a) aliphatic, cycloaliphatic or aromatic polyisocyanates, b) heterofunctional hydrogenated monomers having general formula:X0-(CR1AR2A)b-Y0 one or more of the following compounds: c) bifunctional hydroxyl (per)fluoropolyethers (PFPE diols) having number average molecular weight in the range 400-3,000, e) monofunctional hydroxyl (per)fluoropolyethers or monofunctional hydroxyl (per)fluoroalkanes (e'), having number average molecular weight in the range 300-1,000, and optionally the following compunds: d) heterofunctional monomers, dI) hydrogen-active compounds, capable to form bonds with the NCO functions stable at the hydrolysis but weak at heat.
