Latest Patents

Alfredo Lopez Carretero holds a patent for a method of making polycarbonate. This method involves polymerizing an aromatic dihydroxy compound and a diaryl carbonate in the presence of a polymerization catalyst. The process produces a by-product vapor stream that includes the dihydroxy compound, diaryl carbonate, and a diaryl carbonate by-product. By adding a low vapor pressure compound to the by-product vapor stream, he creates a modified by-product vapor stream. This stream is then introduced to a separation unit where the volatile diaryl carbonate by-product is removed, resulting in a treated by-product stream that is returned to the polymerization reaction. This innovative approach not only improves the production process but also addresses waste management in polycarbonate manufacturing.
