This paper describes the synthesis of amphiphilic block copolymers by living radical polymerization (NMP) of new styrene-like monomers. The polar monomers (ethylene oxide side chains and free hydroxyl- or amino-groups after deprotection) were polymerized in a “”protected form”” to adjust the solubility of the monomers. In this way high molar mass polymers with a narrow polydispersity (around or below 1.2) were accessible. By exposing thin films of these polymers to vacuum (air) or alternatively to water or a hydrophilic surface it becomes possible to switch the surface polarity reversibly between contact angles of about 105° and 83° as a result of surface reconstruction. Through side chains of different length and with different functionalities, it was possible to adjust the glass transition temperatures to values between -2° to 140° for the hydrophilic blocks and -30° to 100° for the hydrophobic block. The wide range of the glass temperatures allowed it to find a block copolymer system with a slow kinetic concerning the surface reconstruction process, so that a mechanistic examination of the process by AFM was possible. It got, thereby, possible to detect the break-up of the hydrophobic surface lamella and the upfold of the hydrophilic lamella in contact with water.2-(2-Chloroethoxy)ethyl acetate(cas: 14258-40-3Product Details of 14258-40-3) was used in this study.
2-(2-Chloroethoxy)ethyl acetate(cas: 14258-40-3) belongs to aliphatic hydrocarbons. Aliphatic hydrocarbons belong to the most abundant fraction in crude oil. Aliphatics molecules are linear or branched open-chain structures such as n-alkanes, isoalkanes, cycloalkanes (naphthenes), terpenes and steranes.Product Details of 14258-40-3
