Abstract
1389210 Sulphonated macroreticular resins ROHM & HAAS CO 20 Dec 1971 [28 Dec 1970 22 Nov 1971 6 Dec 1971] 27127/74 Divided out of 1389209 Heading C3P The invention comprises sulphonation products of macroreticular resins which are copolymers of a heterocyclic nitrogen monomer and a cross-linking aromatic monomer, especially copolymers of (i) 20-60 wt. per cent of a polyvinyl aromatic hydrocarbon monomer, e.g. di- or tri-vinyl benzene and (ii) 80-40 wt. per cent of a vinyl nitrogen heterocyclic monomer, e.g. vinyl pyridine. Up to half of the latter may be replaced by another monomer, of which many are specified. Examples describe the sulphonation, with 99% H 2 SO 4 or a mixture thereof with ethylene dichloride, of macroreticular copolymers of 4-vinyl pyridine, divinyl benzene and ethyl vinyl benzene.
