Oxadimethacrylics useful for preparing pollers have the general formula I CH2=C(A)CH2-O-CH2C(B)=CH2 I where A and B are selected from the group consisting of -COOR1, -COR1, -CONR2R3 and -CN with the proviso that A NOTEQUAL B, and R1, R2 and R3 are each defined as follows: R1 is hydrogen, C1-C18-alkyl, C3-C8-cycloalkyl, C3-C8-cycloalkyl-C1-C5-alkyl, wherein the cycloalkyl rings may be C1-C4-alkyl- or C1-C4-alkoxy-monosubstituted, -disubstituted or -trisubstituted, hydroxy-C1-C5-alkyl, amino-C1-C5-alkyl, N-C1-C4-alkylamino-C1-C5-alkyl, N,N-di-(C1-C4-alkyl)amino-C1-C5-alkyl, C6-C18-aryl, C6-C18-aryl-C1-C4-alkyl, wherein the aryl groups may carry up to three of the following groups: halogen, C1-C22-alkyl, C1-C4-alkoxy, carboxyl, C1-C4-alkoxycarbonyl, aminocarbonyl, C1-C4-alkylaminocarbonyl, di(C1-C4-alkyl)aminocarbonyl, nitrilo, nitro, amino, C1-C4-alkylamino, di(C1-C4-alkyl)amino; R2 and R3 are each hydrogen, C1-C18-alkyl, C3-C8-cycloalkyl, C3-C8-cycloalkyl-C1-C5-alkyl, wherein the cycloalkyl rings may be C1-C4-alkyl- or C1-C4-alkoxy-monosubstituted, -disubstituted or -trisubstituted, C8-C18-aryl, C8-C18-aryl-C1-C4-alkyl, wherein the aryl groups may carry up to three of the following groups: halogen, C1-C22-alkyl, C1-C4-alkoxy, carboxyl, C1-C4-alkoxycarbonyl, aminocarbonyl, C1-C4-alkylaminocarbonyl, di(C1-C4-alkyl)aminocarbonyl, nitrilo, nitro, amino, C1-C4-alkylamino, di(C1-C4-alkyl)amino.
