Aluminum alkoxide or aluminum aryloxide is produced by dissolving aluminum in gallium and/or gallium-based alloy wherein the gallium and/or gallium-based alloy is in a liquid form. The aluminum is then reacted with an organic compound having at least one reactive hydroxyl group to thereby obtain the aluminum alkoxide or aluminum aryloxide.

Process for producing aluminum alkoxide or aluminum aryloxide

The invention is a room-temperature dry process for texturing copper on polyester, to improve adhesion of coatings to the copper surface through mechanical as well as chemical bonding. An iodine plasma is produced by backfilling an evacuated chamber with iodine and applying an RF potential. The iodine plasma includes both positive and negative iodine ions. Unprotected surface areas of the copper form a copper iodide; when the copper iodide is removed, the remaining surface is highly textured. The associated polyester is not damaged. The copper iodide is conveniently removed by a 10% hydrochloric acid solution which has no damaging effects on the associated polyester or on the metallic copper, or on associated polyester in a plastic laminated with copper.
