<p>PROCESS FOR THERMALLY STABILIZING A POLYMER CONTAINING RESIDUES OF A SN(II), SB(III), PB(II), BI(III), FE(II), TI(II), TI(III), MN(II), MN(III), OR GE(II)-CONTAINING CATALYST BY TREATING THE POLYMER AT A TEMPERATURE ABOVE ITS MELTING TEMPERATURE WITH A PEROXIDE SELECTED FROM THE GROUP CONSISTING OF KETONE PEROXIDES, HYDROPEROXIDES, PERACIDS, HYDROGEN PEROXIDE, AND MIXTURES THEREOF, WHEREIN SAID PEROXIDE IS USED IN AN AMOUNT LESS THAN 0.2 WT % BASED ON THE WEIGHT OF THE POLYMER AND WHEREIN THE MOLAR RATIO OF PEROXY FUNCTIONALITIES FROM SAID PEROXIDE (P) TO METAL (M) RANGES FROM 1 TO 100; SAID METAL (M) BEING SELECTED FROM THE GROUP CONSISTING OF SN(II), SB(III), PB(II), BI(III), FE(II), TI(II), TI(III), MN(II), MN(III), AND GE(II). THE INVENTION FURTHER RELATES TO A METHOD FOR DETERMINING THE METAL RESIDUE CONTENT OF A POLYMER.</p> |
