Abstract
At least 95% tetrahydrofuran soluble polymers are obtainable by copolymerization of a monomer mixture of PA0 A) from 1 to 99% by weight of at least one at least 98% pure monomer of the general formula I EQU CH.sub.2 .dbd.C(E)CH.sub.2 --O--CH.sub.2 C(E').dbd.CH.sub.2 I PA0 where E and E' have been selected from the group consisting of --COOR.sup.1, --COR.sup.1, --CONR.sup.2 R.sup.3 and --CN and R.sup.1, R.sup.2 and R.sup.3 are each defined as follows: PA1 R.sup.1 =H, alkyl, cycloalkyl, cycloalkylalkyl, wherein the cycloalkyl rings may be alkyl- or alkoxy-monosubstituted, -disubstituted or -trisubstituted, hydroxyalkyl, aminoalkyl, alkylaminoalkyl, dialkylaminoalkyl, aryl, arylalkyl, wherein the aryl groups may carry up to three of the following groups: halogen, alkyl, alkoxy, carboxyl, alkoxycarbonyl, aminocarbonyl, alkylaminocarbonyl, dialkylaminocarbonyl, nitrilo, nitro, amino, alkylamino, dialkylamino; PA1 R.sup.2, R.sup.3 =H, alkyl, cycloalkyl, cycloalkylalkyl, wherein the cycloalkyl rings may be alkyl- or alkoxy-monosubstituted, -disubstituted or -tri-substituted, aryl, arylalkyl, wherein the aryl groups may carry up to three of the following groups: halogen, alkyl, alkoxy, car…
