Automated Parallel Anionic Polymerizations: Enhancing the Possibilities of a Widely Used Technique in Polymer Synthesis

Guerrero-Sanchez, Carlos; Abeln, Caroline H.; Schubert, Ulrich S.
- Abstract:
- Anionic polymerization techniques have been implemented successfully in
a commercial automated synthesizer. The main problems for a successful adaptation
of the experimental technique in the automated synthesizer are addressed, as well as
some simple potential applications, such as the anionic polymerization of styrene, isoprene,
and methyl methacrylate. The obtained results were reproducible and in concordance
with literature knowledge. The apparent rate constant of the anionic polymerization
of styrene in cyclohexane initiated by sec-butyllithium could be determined
at two different concentrations of the monomer and initiator in a temperature
range of 10–60 8C. All the synthesis and characterization experiments of the polymers
were performed within a short time period. Moreover, the syntheses of poly
(styrene-b-isoprene) and poly(styrene-b-methyl methacrylate) block copolymers were
also successfully carried out within the automated synthesizer.
