Abstract
Official abstract text for this publication.
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.
First claim
Opening claim text (preview).
What is claimed is: 1. A composition comprising: a cyanate ester thermoset polymer; and 1 wt % to about 35 wt % of hollow microspheres homogenously dispersed in the composition, wherein the composition is made by: providing a cyanate ester compound; initiating crosslinking of the cyanate ester compound; stirring the initiated cyanate ester compound until the polymerization reaches the B-stage; adding hollow microspheres to the B-stage polymer; and mixing the B-stage pol…
