All BAPO derivatives can additionally act as electron acceptors, as indicated by cyclic voltammetry and EPR spectroscopy. Thermal-imaging experiments show substantial monomer-dependent exothermicity. The heat profiles of selected photopolymerizations have been observed using a high-resolution infrared camera. Low fluorescence quantum yields of 0.1–0.3 % reveal that the studied BAPOs undergo efficient intersystem crossing, followed by α-cleavage. All phosphanoyl radicals have been found to react the most rapidly with styrene and the most slowly with butyl acrylate. Rate constants for the addition of these radicals to the double bonds of butyl acrylate, methyl methacrylate, 1-vinyl-2-pyrrolidone, and styrene have been determined. the following universities are entitled to submit applications: the Technical University of Vienna (TU Wien), the Technical University of Graz (TU Graz).

A series of new bis(acyl)phosphane oxide (BAPO) photoinitiators has been synthesized and tested with respect to their efficiency in the initiation step of radical photopolymerizations. Come and visit our Tissot store in Graz and be captivated by our brands expertise, which dates back to 1853, and the varied.
