摘要：

The utility of 31P magic angle spinning (MAS) nuclear magnetic resonance (NMR) for the identification of organophosphite polymer additives, their hydrolysis products, and for the determination of their concentration is demonstrated for bis‐(2,4‐di‐t‐butylphenyl) pentaerythritol diphosphite (BTBP) in polycarbonate. This additive undergoes a complex process of hydrolysis that leds to the formation of at least three new phosphous species. High‐resolution solution 31P NMR is used to help in the identification of the products of the stailizer chemistry. Copyright © 1990 John Wiley & Sons, Inc.
