Abstract：
 The present invention is process of optically grafting long fatty carbon chain pyridine salt to the surface of polymer, and belongs to the field of polymer technology. The process includes adding solvent acetone, dichloromethane or acetonitrile to 4-vinyl pyridine and adding fatty halide for reflux reaction to obtain product A; compounding grafting solution with deionized water as solvent, the product A and photoinitiator; soaking the polymer in the grafting solution and irradiating with ultraviolet ray for reaction; extracting the grafted polymer with mixed solvent of water and acetone and drying. The process is simple, low in reaction temperature and low in product cost, and the prepared polymer with grafted long fatty carbon chain pyridine salt in the surface is used as antibiotic material for clothing, appliance, sanitary ceramic product, paint, etc.
