In industrial processes polyacrylates are produced almost entirely by free radical
polymerization. For this process common initiators are peroxides or azo compounds.
These can be activated thermically or through irradiation.
The challenge for the production of polyacrylates is the control of free radical
polymerization. This reaction starts spontaneously with a heat of polymerization around
60-80 kJ/mol acrylate.
DSC experiments at different temperatures have been recorded for the polymerization
of n-butylacrylate to monitor the reaction kinetics. With the obtained data the necessary
cooling capacities of a pilot plant scale reactor have been calculated
