Procedure

1.52 g of fumaryl chloride in 200 ml of methylene chloride are polycondensed, analogously to Example 2, with 2.47 g of lysine ethyl ester dihydrochloride and 2.75 g of lysine butyl ester dihydrochloride in 200 ml of water which contains 5.5 g of potassium hydroxide. 2.5 g (71% of theory) of white, fiber-like copolycondensate are obtained.
