METHOD OF REDUCTION OF CONTENT OF OLIGOMERIC CYCLIC ETHERS IN THE PRODUCT OF POLYMERIZATION OF TETRAHYDROFURAN AND ALKYLENE OXIDEH EHFIROV V PRODUKTE POLIMERIZACII TETRAGIDROFURANA I OKISI SLKILENA

摘要

The oligomeric cyclic ether content of a tetrahydrofuran/alkylene oxide polymerizate is significantly reduced by bringing the polymerizate into contact with an acid-activated sodium or calcium montmorillonite clay.
