CARBONATE POLYMER COMPOSITIONS STABILIZED AGAINST DISCOLORATION AND PHYSICAL PROPERTY DETERIORATION DURING STERILIZATION BY IONIZING RADIATION

摘要

Disclosed are carbonate polymer compositions comprising a poly(oxyalkylene) derivative, a free di-sulfonimide, and optionally a salt and methods of preparation for said compositions. Such carbonate polymer compositions exhibit good color stability and physical property retention when irradiated with ionizing radiation for sterilization.
