Procedure

Styrene (102.96 g) (0.99 mol), 44.2 g (0.21 mol) of vinylbenzyltrimethylammonium chloride and 446 g of 2-methoxy-ethanol were put in a three necked flask and heated at constant temperature of 75° C. with stirring under nitrogen gas flow. Thereafter, 76 g (12 mmol) of 2,2-azobis(dimethyl-2-isobutyrate) was added to the above solution, followed by stirring. After 2 hours, 76 g (12 mmol) of 2,2-azobis(dimethyl-2-isobutyrate) was further added. Further, after 2 hours, 2.76 g (12 mmol) of 2,2-azobis(dimethylisobutyrate) was added. After stirring the reaction solution for 2 hours, the temperature was lowered to room temperature. This reaction solution was poured into 12 liters of hexane with stirring. The solid precipitated was filtered and dried. The yield was 189.5 g. The obtained solid was confirmed to have a weight average molecular weight (Mw) of 32,000 from the molecular weight measurement by a light scattering method. Other polymer compounds for use in the present invention can also be synthesized by similar methods.
