PDF Tromsdorff Effect (or Auto-acceleration) - MIT OpenCourseWare • mit.edu

Tromsdorff Effect (or Auto-acceleration) Auto-acceleration usually occurs in radical chain polymerizations and normally in bulk polymerization. As conversion (π) increases, the viscosity (η) increases so much that the ends cannot find each other to terminate polymerization. This in turn lowers the effective termination rate (k

Autoacceleration - SpringerLink • springer.com

Autoacceleration (Gel Effect, Trommsdorff-Norrish Effect) is a dangerous reaction behavior that can occur in free radical polymerization systems. It is due to the localized increases in viscosity of the polymerizing system that slow termination reactions. The removal reaction obstacles therefore causes a rapid increase in the overall rate of ...

The autoacceleration phenomena known as the Trommsdorff-Norrish effect is well-known in polymer chemistry of some vinyl monomers such as acrylate and methacrylate derivatives [1], [2], [3].Though the phenomenon was found and has been studied for many decades, there is a general tendency that polymer researchers try to avoid this complicated phenomenon because of its highly nonlinear ...

The terms Trommsdorff effect and Norrish-Smith effect are also used in recognition of the early workers in the field. Similar behavior has been observed for a variety of monomers, including styrene, vinyl acetate , and methyl methacrylate [Balke and Hamielec, 1973 Cardenas and O Driscoll, 1976, 1977 Small, 1975 Turner, 1977 Yamamoto and ...
