Perfluoroalkylated diblock-alkyl methacrylate monomers for biomedical applications: Wettability of their copolymers with HEMA and DEGMA

The intermediate perfluoroalkylated diblock hydrophobic–hydrophilic secondary alcohols (9–11), which were prepared by the reaction of monomethyl ethers of oligomeric ethyleneglycols with 2-[(perfluoroalkyl)methyl]oxiranes (7 and 8), resulted in the formation of the title monomers (12–14) by the acylation with methacryloyl chloride. Copolymers of 12–14 with HEMA and DEGMA prepared under radical conditions display enhanced swelling properties.
