Beschreibung
Zusammenfassung:	A photochromic polymer comprising at least two photochromic moieties linked by a straight or branched chain polymer selected from the group consisting of a homo- polyester, a co-polyester, and a co-polyester-polyether. L'invention concerne un polymère photochrome comprenant au moins deux fractions photochromes reliées par un polymère linéaire ou ramifié choisi dans le groupe constitué par un homo-polyester, un co-polyester et un co-polyester-polyéther.
