Abstract:

The investigation demonstrated the fact that many different forms of polymerized trimethyl dihydro quinoline are available and that the 150C. oven aging characteristics of cross-linked polyethylene are sometimes affected by which of the various forms is employed. Thorough dispersion of the antioxidant is critically essential. Melting point, by itself is, in general, of little consequence and the volatile loss of antioxidant is of somewhat minor significance. Indications were shown that some parameters other than those discussed here are involved in the effectiveness of PTDQ as a high temperature antioxidant for cross-linked polyethylene. Although this work here was entirely on cross-linked polyethylene and polymerized trimethyl dihydroquinoline the principles involved should clearly apply to other polymerantioxidant systems. Author
