Claims Analysis
Total Claims: 2
Claim 1
Independent Claim
80 words
ESTERS BETWEEN AN ACYCLIC POLYOL AND TRIMERIC METABORIC ACID, SAID POLYOL HAVING 3 TO 10 CARBON ATOMS AND 2 TO 3 HYDROXYL GROUPS ATTACHED TO CARBON ATOMS, EACH OF SAID HYDROXYL GROUPS BEING SEPARATED FROM ITS NEIGHBORING HYDROXYL GROUP BY 3 TO 6 CARBON ATOMS AND UP TO ONE NITROGEN ATOM, THE TOTAL NUMBER OF ATOMS SEPARATING SAID NEIGHBORING HYDROXYL GROUPS BEING 3 TO 6, IN WHICH ALL OF THE HYDROXYL GROUPS OF SAID POLYOL ARE BONDED TO SAID ACID.
