We have synthesized a series of fluorinated side chain block copolymers based on either a hydroborated polystyrene-b-polyisoprene or a poly(methyl methacrylate)-b-poly(2-hydroxyethyl methacrylate) backbone. Through polymer-analogous reactions, perfluorinated ester, fluorinated urethane, and fluorinated carbonate side chains were attached to the pendant hydroxyl groups. Their selective thermal degradation behavior was investigated using thermogravimetric analysis (TGA) and thermal desorption mass spectrometry (TDMS). In addition, we investigated the heat- and laser-induced selective alteration of polymer film surfaces by chemically highly selective cleavage of the fluorinated side chains using X-ray photoelectron spectroscopy (XPS), FT-infrared spectroscopy (FT-IR), and contact angle measurements. Finally, we demonstrate the potential to create a laterally patterned surface with different regions of chemically well-defined surface moieties from our fluorinated block copolymers by a dry laser process.

Some silyl ether derivatives of 2-hydroxyethyl methacrylate (HEMA) were prepared. The Et3Si, Ph3Si and Me3Si groups together with cubane-1,4-dicarboxylic acid (CDA) were covalently linked with HEMA. The silyl-linked HEMA are abbreviated as TETMA, TPhMA and TMEMA, respectively. CDA linked to two HEMA groups is the cross-linking agent (CA). Free radical copolymerization and cross-linking copolymerization of the resulting monomers with 2-hydroxyethyl methacrylate (HEMA) with the various ratios of CA as cross-linking agent, were carried out using AIBN as initiator at the temperature ranges 60-70 °C. The cross-linking copolymers were identified by FT-IR spectroscopy. The glass transition temperature (T g) of the network polymers was determined calorimetrically. The Tg of network polymers increases with increase of cross-linking degree. All monomers and polymers were identified by spectroscopic methods. These silyl derivatives modified methacrylate polymer properties.
