摘要 |
<p>PCT No. PCT/BE96/00091 Sec. 371 Date Jul. 9, 1998 Sec. 102(e) Date Jul. 9, 1998 PCT Filed Aug. 28, 1996 PCT Pub. No. WO97/09358 PCT Pub. Date Mar. 13, 1997The invention concerns a process for preparing powdery ionomers by neutralizing a powdery precursor using a neutralizing agent. A particular feature of the invention is that the precursor is used in a powder form and a concentrated aqueous solution of neutralizing agent is rapidly mixed with the precursor, and that the neutralized ionomer essentially retains the dry powder form and size of a precursor while having a water content of about 10%. The resulting product can be used as a wear layer for producing ground and wall coverings, either by powder deposition process or by extension to form a film, which is applied in a hot state to a support.</p> |
