Abstract
Disclosed herein is a composition having a thermoset polymer and a plurality of hollow microsphere homogenously dispersed in the composition. The polymer is a cyanate ester thermoset, a phthalonitrile thermoset, a crosslinked acetylene thermoset, or a hydrosilation thermoset. Also disclosed herein is a method of: providing a thermosetting compound; adding microspheres to the thermosetting compound; and mixing the thermosetting compound while initiating crosslinking of the thermosetting compound.
