An alkoxylpropyl isothiazolinone of formula: C<SUB>6</SUB>H<SUB>6</SUB>Cl<SUB>2</SUB>NO<SUB>2</SUB>SR, in which R is CH<SUB>3</SUB>, CH<SUB>2</SUB>CH<SUB>3</SUB>, CH(CH<SUB>3</SUB>)<SUB>2</SUB>, CH<SUB>2</SUB>CH<SUB>2</SUB>CH<SUB>2</SUB>CH<SUB>3</SUB>, CH<SUB>2</SUB>CH<SUB>2</SUB>OCH<SUB>3 </SUB>or CH<SUB>2</SUB>CH<SUB>2</SUB>OC<SUB>6</SUB>H<SUB>5</SUB>Cl. A method for preparing the isothiazolinone by reacting sodium polysulphide with methyl acrylate to obtain dimethyl dithiodipropionate, followed by aminolysis with alkoxyl propylamine to obtain N,N'-dialkoxylpropyldithio-dipropionamide, which is then reacted with sulfuric chloride. The alkoxylpropyl-isothiazolinone of the invention can be used for preparing marine antifouling paint coating as antifoulant, and also used as bactericide.
