Abstract: PROCESS FOR PREPARING A POLY(METH)ACRYLIC ACID ESTER HAVING A HIGH ISOTAXY AND A NARROW MOLECULAR WEIGHT DISTRIBUTION ( HOE 76/F 214 ) of the disclosure: Esters of the (meth)acrylic acid may be polymerized with the aid of free radical forming or ionically effective initiators. The stereospecificy of the polymers may be influenced by the selection of specific initiators; magnesium-organic compounds are suitable for the synthesis of isotactic polymers. Poly(meth) acrylic acid esters having a high isotaxy and a narrow molecular weight distribution (polydispersity) are obtained with the aid of substituted phenylmagnesium halides. They are suitable as gauge and as test substances.
