PURPOSE: Provided are perfluorinated hydrocarbon polymers which can be used as fillers for the preparation of adhesive formulations having excellent dielectric properties, i.e., very low conductivity. This compositions display excellent rheological properties, in addition to low dielectric constants. The formulations can be used for a variety of purpose such as, for example, for the preparation of filled adhesive formulations with a reduced propensity to settle out, excellent dispensing characteristics due to the thixotropic nature thereof and the like. CONSTITUTION: The composition comprises a polymerizable monomer vehicle which, upon cross-linking, possesses good adhesion properties, wherein the vehicle is a maleimide, a (meth)acrylate, a propargyl ether material, an isomerized propargyl ether material, or a mixture of any two or more thereof; a perfluorinated hydrocarbon polymer having a particle size of 0.1-100 micrometer, a surface area of 0.2-20 g/m2 and a bulk density of at least 100 g/L; a curing catalyst.
