WebBzMA (3.0 g) under stirring. Subsequently, ethyl α-bromoisobutyrate (EBIB) (0.04 g) and DABCO (0.43 mg) was introduced in the solution. The polymerization was performed at 50 ºC for 12 hours under Argon. The reaction was terminated by THF, passed through a neutral aluminum oxide column, precipitated in methanol and the product dried under vacuum. WebJun 29, 2016 · We report a systematic study of the plasma polymerization of ethyl α-bromoisobutyrate (EBIB) to produce thin film coatings capable of serving as ATRP initiation surfaces, for which they must contain α-bromoisobutyryl functional groups. In the deposition of polymeric coatings by plasma polymerization …
