Reaktionsschritte

The same reactor as used in Example 1 was charged with 30 g of N-vinylpyrrolidone, 104 g of triphenyltin chloride and 200 g of xylene, and the mixture was stirred at 50° C. for 2 hours to form an N-vinylpyrrolidone/triphenyltin chloride adduct. Then, 50 g of butyl acrylate, 16 g of octyl acrylate and 0.5 g of benzoyl peroxide were added, and with stirring, the mixture was heated to 75° C. At this temperature, 0.2 g of benzoyl peroxide was added three times at intervals of 3 hours, and the polymerization reaction was carried out for a total of 12 hours to give an N-coordinated-triphenyltin-containing copolymer solution having a molecular weight of 77,000 (to be referred to as a copolymer solution [A-18]). This copolymer solution was used directly as an antifouling agent.
