    摘要: The invention relates to carbodiimide-based block copolymers, a method of preparing them and also their use as hydrolysis stabilizers in ester-group-containing polymers. The advantages of the block copolymers according to the invention are, in particular, their high efficiency at low dosage as hydrolysis protection in ester-group-containing polymers, and also their nontoxic behavior, their high thermal stability and their good compatibility during incorporation in the polymeric matrix of the polymers to be protected.
