Process for making microporous products and the products thereof. |
摘要 |
<p>A process of producing a structural network from a semicrystalline, melt crystallisable polyarylene ether or polyarylene thioether comprising providing a molten mixture of at least one semicrystalline polymer in the presence of a melt plasticiser for the polymer which melt contains at least some polymer entities having a crystalline form, the total polymer concentration being between 5 and 50% by weight of the mixture of polymer and melt plasticiser, and heating the mixture of polymer and melt plasticiser at a heating rate of between 1 DEG C/hour and 1000 DEG C/hr, preferably between 10 DEG C/hour and 100 DEG C/hour until the mixture is at a temperature in the range 10 DEG C below to 20 DEG C above its clearing point and cooling the mixture until it solidifies whereby an open cell structure essentially free from granular superstructure is obtained.</p> |
