| Zusammenfassung: | Chlorinated, brominated and/or nitrated phenyl (meth)acrylates are prepd. by mixing >=1 of the corresp phenols together with SO2Cl and a Lewis acid with an inert diluent and leading (meth)acrylic acid into this mixt. with stirring. HCl and SO2 as well as non-reacted reaction components and diluent are then sepd. from the crude ester prod. The phenyl, esters are used in the prepn of cross-linked copolymers with other ethylencially unsatd. cpds. |
