Abstract
Inventia se refera la un procedeu de spurificare a polieterilor polioli pentru spume poliuretanice prin poliaditia unui alchilenoxid la un poliol în cataliza bazica, prin tratarea cu 1...10% în greutate bentonita calcica, procedeu conform caruia, pentru îmbunatatirea filtrarii se utilizeaza, ca adjuvant de filtrare, 0,5...3% în greutate tuf vulcanic de tip vitrocristaloelastic, cu continut de 80...100% sticla, tratat cu acid clorhidric.
