 · Radical polymerization of acrylic monomers An overview Progress in Polymer Science ( IF 22.620) Pub Date DOI Nicholas Ballard Jose M. Asua Since their discovery and development in the 20th century acrylic polymers have become an integral part of numerous industries and are used in a myriad of applications.  · The purpose of this study is to obtain a better understanding of Michael addition reaction (MAR) which may induce runaway polymerization of acrylic acid. The heat of MAR was measured using a C80 Calvet-type heat flux calorimeter and products of MAR were revealed by gel permeation chromatography. The reaction rate constant of MAR was obtained from kinetic analysis.

 · The reactor configuration used for this process should be a packed bed reactor. Details about the design of the reactor are given in the Appendix of this problem statement. Safety Considerations It is recommended that the steam-to-propylene ratio at the reactor inlet never be  · Thus runaway reaction can easily occur since the reactor temperature is very difficult to control which also can lead to a non-uniform product. For these reasons most acrylic resin products are produced by using one of the other polymerization processes.
