Abstract
Aluminum-containing resins are produced by reactively contacting resin-forming monomers in the presence of aluminum metal which has been activated by permeation of high purity aluminum with mercury, gallium or an alloy of indium and gallium. In certain cases a co-catalyst, such as a halogen, is utilized.
Claims8
A method of preparing an aluminum containing resin which comprises:
- contacting and reacting under resin promoting conditions
- I. activated aluminum comprising high purity aluminum metal activated through permeation with a metal selected from mercury, gallium and indium/gallium alloys and
- Ii. a resin forming alkenylbenzene monomer system
- said activated aluminum being present in an amount effective to catalyze the resin formation and to introduce into the formed resin up to 5.0% by weight aluminum;
- and
- terminating the resin formation reaction by withdrawing unreacted aluminum from the reaction system.
