Latest Patents

Mohanraj holds a patent for a method of chlorinating methyl groups of methyl vinyl aromatic polymers. This method involves chlorinating the pendant methyl groups of poly(p-methylstyrene) using aqueous sodium hypochlorite, commonly known as laundry or swimming pool bleach, along with a phase transfer catalyst such as benzyltriethylammonium chloride. The process achieves conversions of up to 20 percent of methyl to chloromethyl groups without detectable formation of dichloromethyl groups. Furthermore, conversions of up to 61 percent of methyl to chloromethyl groups can occur with less than 4.4 percent concomitant formation of dichloromethyl groups. This method has been successfully applied to soluble, 1 percent cross-linked, and macroporous 20 percent cross-linked polymers.
