<p>Polyethersulfone is densified by preparation of a homogeneous paste with a semi-solvent, which may be drawn off by heating and vacuum, from an emulsion prepared from the paste. The resulting PES is substantially densified, with a reduced surface area. The densified PES can be added in significant amounts to thermosetting resin preparations, without a substantial increase in viscosity.</p> |
