HCID 161524Furan-2,5-dione--2-methylprop-1-ene (1/1)

Procedure

The formed particulate matter was collected by centrifugation and dried to obtain 4.4 kg of realistic anhydride/isobutene copolymer. The resulting copolymer contained 50 mole % of succinic anhydride units according to elemental analysis, and had relative solution viscosity of 2.0 (measured in N,N-dimethylformamide solvent at 23° C. with an Ubbelohde viscometer).
