- Abstract:
- The use of microwave heating in polymer science
is a rapidly growing field of research leading to faster and
cleaner polymerization procedures. However, the majority of
the investigations are performed at small scales (1 mL),
which is far away from potential commercial applications of
microwave-assisted polymerizations. In addition, it has been
shown in organic chemistry that microwave-assisted reaction
protocols can be directly scaled without the need for process
optimization. In this contribution, we have investigated the
direct scaling of microwave-assisted polymerization procedures
under pressure conditions using the cationic ringopening
polymerization of 2-ethyl-2-oxazoline as the model
system. This polymerization was performed at scales ranging
from 4.0 mmol (1 mL) to 1.0 mol (250 mL) in different
microwave synthesizers covering both monomode and multimode
devices.
