Abstract: A process for the preparation of infusible, solvent-insoluble, solvent-dispersible, inherently tacky elastomeric polymeric microspheres without the use of a suspension stabilizer comprising the steps of: (a) charging to a reaction vessel: (1) at least one alkyl acrylate or methacrylate ester monomer; (2) at least one emulsifier at a concentration above its critical micelle concentration; and (3) an effective amount of at least one substantially water insoluble polymerization initiator; (b) agitating the reaction vessel charge prior to the initiation of the reaction sufficient to create a suitable monomer/water emulsion in the reaction vessel; and (c) maintaining the agitation for a time sufficient to allow substantially complete conversion of the monomer. This process forms elastomeric, solvet-dispersible, polymeric micropheres.

Abstract: Epoxy resin is mixed with a salt of bis(fluoroalkylsulfonyl)methane or fluoroalkylsulfonic acid as a latent catalyst, phosphorus pentoxide, and a base (which acts as an acid scavenger for phosphoric acids resulting from hydration of the phosphorus pentoxide), to provide a one-part, latent, moisture and room temperature curable epoxy resin composition.
