Abstract

1415676 Ion exchange DUNLOP Ltd 10 Nov 1972 [2 Dec 1971] 51915/72 Heading B1J [Also in Division C3] Particulate scrap vulcanised rubber having substituent ionogenic groups is used as an ion exchange material. Examples are given of the use of rubber powder or SBR foam containing -SO 2 H or -SO 3 H groups in cation exchange methods and of rubber powder containing -COOH, -PO(OH) 2 , -NEt 3 OH or -NMe 3 OH groups in anion exchange methods.
