The configuration of citraconic (~-methylmaleic) anhydride units in styrene/citraconic anhydride copotymers prepared in methyl ethyl ketone at 50.0 + 0. V was determined over a wide range of comonomer feed compositions using ~3C-NMR spectroscopy. It was found that the ratio of Z (zusammen) to E (ent
## Abstract The composition and monomer unit sequence distribution of copolymers of __p__βchlorostyrene (__p__βCST) with citraconic (Ξ±βmethylmaleic) anhydride (CA) prepared in methyl ethyl ketone (MEK) at 50,0 Β± 0,1Β°C were determined over a range of comonomer feed mole fractions using ^13^C NMR spe
Radical copolymerizations of citraconic acid (CA) derivatives including citraconic anhydride (CAn), N-alkylcitraconimides (RCIs), dialkylcitraconates (DRCs) and dialkyl mesaconates (DRMs) with vinyl acetate (VAc) were performed in bulk at 60 Β° with 0.02 mol.dm 3 of 2,2'-azobisisobutyronitrile.
