ZUSAMMENSETZUNG MIT OLEFINISCH UNGESAETTIGTEN VERBINDUNGEN UND HYDRAZONEN

摘要

Compositions of this kind begin to polymerize as soon as the components are mixed together. In order to widen their field of application, they have been made stable to storage. To this end, O2 and peroxides must be removed. Suitable ways of doing this are degassing and the addition of a deoxidizing agent. This makes controlled polymerization possible: thus adhesives and sealing, coating and moulding compounds, for instance, can first be rendered storage-stable for a period of several months, which is a suitable length of time for normal use, and they will then cure within an hour at room temperature simply on admission of air.
