Abstract:
1. A fluorinated methacrylate polymer composition comprising repeating units in any sequence from (1) at least one fluorinated methacrylate, and (2) at least one non-fluorinated alkyl acrylate and (3) at least one non-fluorinated hydroxyalkyl methacrylate, provided that a) the repeating unit of fluorinated methacrylate is present in a range of from 40% to 80% by weight of total monomers added, b) the repeating unit of non-fluorinated alkyl acrylate is present in a range of from 10% to 35% by weight of total monomers added, and c) the repeating unit of non-fluorinated hydroxyalkyl methacrylate is present in a range of from 5% to 25% by weight of total monomers added, and d) the total of all repeating units is 100% by weight; wherein the fluorinated methacrylate is: CF 3 (CF 2 ) 5 —CH 2 CH 2 —OC(O)—C(CH 3 )═CH 2 , the non-fluorinated alkyl acrylate is stearyl acrylate, the non-fluorinated hydroxyalkyl methacrylate is 2-hydroxyethyl methacrylate, and the fluorinated methacrylate polymer composition is solvent-based and non-aqueous.
