Abstract
Abstract Two-part polymerizable compositions are described which contain (a) organic material having epoxide functionality, (b) organic material having hydroxyl functionality, and (c) a catalyst comprising highly fluorinated aliphatic sulfonyl protonic acid or a compound capable of liberating such acid. The compositions polymerize essentially completely at room temperature (or at slightly elevated temperatures). The polymerized compositions have desirable dielectric properties and are therefore especially useful for potting electrical components.
