2,3-dichlorobuta-1,3-diene

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: A 500 mL reaction flask was charged with 34.5 g of 2,3-dichlorobutadiene and 27.5 g of maleic anhydride. 200 mL of toluene was added, along with a small amount of BHT (0.5 g). The solution was heated to reflux until the reaction was complete. The toluene was removed and the product recrystallized from ethyl acetate/hexanes to give 38.25 g (61.8%) of 4,5-dichlorotetrahydrophthalic anhydride. A 500 mL reaction flask The solution was heated to reflux until the reaction The toluene was removed the product recrystallized from ethyl acetate/hexanes

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 18.0 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, 264.4 g of water was added thereto, and 656.4 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: 1/0.86, total amount of surfactant: 0.74 wt %). was mixed The mixture was left

Conditions: temp:0.00; pressure:0.00; stir:; See reaction.notes.procedure_details.

Procedure: 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 %). was mixed The mixture was left
