Abstract: | Several telomers were prepared by redox catalysis from 2-hydroxyethyl acrylate ( 1 ) and telogens such as carbon tetrachloride, methyl trichloroacetate, 1, 1, 1-trichlorotrifluoroethane, and 2,4,4,4-tetrachloro-2-methylbutyric acid ( 2d ), as well as block-cotelomers from 1 and a telomer 4 prepared from chlorotrifluoroethylene and carbon tetrachloride. Polyols ( 3a–d and 5 ) with two to twenty primary hydroxyl groups were obtained. They were esterified with acrylic acid, to obtain new photosensitive compositions. ( 6a–d ). |
