Reaktionsschritte
3.3 g of sodium lauryl sulfate (Emar 2F Needle (30% concentration), manufactured by Kao Corporation), was added as a surfactant to 295 g of the above 2,3-dichlorobutadiene homopolymer latex (2), and the mixture was thoroughly stirred until it became uniform. Then, 26 g of water was added thereto, and 244.1 g of the resorcinol/formaldehyde mixed liquid prepared as described above, was mixed thereto. The mixture was left to stand and aged at 23° C. for 24 hours to obtain a resorcinol/formaldehyde/latex mixed liquid (the weight ratio of the latex solid content to the sum of resorcinol and formaldehyde: 1/137, total amount of surfactant: 0.83 wt %).
