## Abstract New photochromic polymers were prepared by deactivating living homo or block copolymers with various 2__H__‐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 phot

## Abstract On a synthétisé à l'aide de la technique de polymérisation par voie anionique, des copolymères séquencés polystyrène/polyvinyl‐4 pyridine. On a opéré sous vide, en milieu tétrahydrofuranne qui est un mauvais solvant, sinon un précipitant, de la polyvinyl‐4 pyridine; l'initiateur utilisé
## Abstract Hydrogenations of several hydroxy‐terminated low molecular weight polybutadienes (PB) or non functional PB and one polyisoprene by homogeneous catalysis were studied. Hydrogenation of 1,4‐polybutadienes gave solid crystalline polymers. In the case of hydrogenated 1,2‐polymers a decrease
