Process for making a foamed polymer |
| 摘要 |
The invention relates to a process for making a foamed polymer. The process involves (a) dispersing thermally degradable solid particles in polymer precursor; (b) crosslinking the polymer precursor to form a rigid, crosslinked polymer without degrading the particles; and (c) heating the polymer to degrade the particles and form the polymer foam.
