Abstract
New photochromic polymers were prepared by deactivating living homo or block copolymers with various 2H‐chromene‐2‐spiro‐2′‐indolines (3a–3d). Classical anionic polymerization was used throughout this work. By varying the chemical nature of the blocks as well as that of the photochromic units, a series of novel materials was obtained and their structure and behaviour were characterized.Keywords
