LATENT CATALYST SYSTEMS FOR CATIONICALLY POLYMERIZABLE MATERIALS

摘要

A multi-component catalyst system that is latent at a first elevated temperature but is rapidly activated at a second temperature only slightly elevated over the first temperature comprises 1) metal salts of fluoroalkane sulfonic acids or bis(fluoroalkylsulfonyl)methanes, and 2) a thermally decomposable ester reaction product of a tertiary alkyl alcohol and an acid that forms a chelation complex with the metal ion of the metal salt. In some embodiments the catalyst system further includes a buffering compound that retards activity of the catalyst system.
