Patent
CA 2342048
The invention relates to carbodiimide-based block copolymers, a method of prepar-ing them and also their use as hydrolysis stabilizers in ester-group- containing poly-mers. 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 behaviour, their high thermal stability and their good compatibility during incorporation in the polymeric matrix of the polymers to be protected.
