Abstract: SILICONE ELASTOMERS ARE DESCRIBED WHICH CONTAIN A HYDROLYTIC DEGARDATIN RESISTANT ADDITIVE WHICH IS AN ADDUCT OR FERRIC CHLORIDE AND AN ORGANIC COMPOUND HAVING THREE AROMTAIC NUCLEI ATTACHED TO ONE ATOM. PREFERRED ADDUCTS ARE THOSE OF FERRIC CHLORIDE WITH TRIPHENYLAMINE OR WITH TRIPHENYL CARBINOL AND A CONVENIENT METHOD OF PREPARING THE FERRIC CHLORIDE/TRIPHENYLAMINE ADDUCT IN SOLUTION IS DESCRIBED. THE ADDUCTS OF THE PRESENT INVENTION INTERFERE WITH THE CROSS-LINKING REACTION OF MOST CURING AGENTS BUT A CLASS OF CURING AGENTS, OF WHICH 2,5-DIMETHYL-2,5-DITERTIARYBUTYL PEROXYHEXANE IS THE BEST MEMBER, WHICH ARE NOT INTERFERED WITH ARE DISCLOSED.
