Abstract
The photoinitiated cross-linking of silicone acrylates is studied by F T-IR spectroscopy. The influences of light intensity, exposure time an d type of photoinitiator are described. The parameters of the kinetic equation are determined. It is shown that oxygen acts as an inhibitor. The asymmetric C=O stretching IR band of the uncross-linked and cross -linked system can be separated into two bands which are attributed to different conformations and geometric arrangements of the acrylate gr oups, respectively.
