Vinylpyrrolidone polymers, their preparation, their use in the preparation of plasma substitutes, and the substitutes thus obtained

摘要

Polymers which due to their physiological compatibility may be used in plasma substitutes and which essentially contain vinylpyrrolidone and alpha , omega -diisocyanato-alkanecarboxylic acid esters as structural units, their preparation, and plasma substitutes containing such polymers.
