- Abstract:
- Automated parallel synthesizers provide fast and comparable screening of
different polymerization parameters under similar conditions. In addition, these
robotic systems eliminate handling errors, which may affect the results of a kinetic
experiment more than the effect of an important parameter. The polymerization temperature
and N,N-tert-butyl-N-[10-diethylphosphono-2,20-dimethylpropyl]nitroxide concentration
were optimized for the homopolymerization of both styrene and tert-butyl
acrylate to improve the control over the polymerization while reasonable polymerization
rates were retained. Subsequently, polystyrene and poly(tert-butyl acrylate) macroinitiators
were synthesized according to the knowledge obtained from the screening
results. These macroinitiators were used for the preparation of block copolymers consisting
of styrene and tert-butyl acrylate.
