  A discarded motherboard based eco-friendly copper catalyst has been
programmed to replace the industrially used tin based catalyst DBTDL. The
catalyst has been characterized by UV-Vis spectroscopy, FT-IR and TEM. Using
the catalyst reaction conditions is optimized and under the optimized
condition, both polyurethane and polyurethane foam are prepared, thus proving
the generality of the catalyst to be used in industries. A possible mechanism
has also been proposed.
