Summary

The compound 4,4'-methylene bis-(2,6-diisopropylaniline), or MDIPA, has shown good thermal stability, high butt tensile strength, and excellent compatibility with salt when used as a curative for LLL's Halthane 87 prepolymer. Laboratory-scale synthesis of MDIPA by condensation of commercially-available 2,6-diisopropylaniline and formaldehyde has been accomplished, using the amine sulfate as an intermediate. Polymer Pilot Plant scale-up has been achieved; kilogram quantities at acceptable purity levels (98+ percent) have been produced.
