Abstract: Poly:sulphonic acid polymers (P) - prepared by the polymerisation of monomers chosen from 8-20C vinyl aromatic compounds or indene (derivatives) of formula (I) in the presence of sulphur trioxide: R=1-6C alkyl;R1-R4=H or 1-6C alkyl;and n=0-3. Also claimed are (i) the preparation of (P) by reacting the above monomers in the presence of sulphur trioxide at 0 - 200 deg C; and (ii) the preparation of aryl sulphonic acid monomers by reacting aromatic hydrocarbons with sulphur trioxide at 0 - 200 deg C, in which the reagents are nebulised by passing them through a nozzle, optionally with an inert gas.

Abstract: In deinking printed waste paper by beating in aqueous medium in the presence of deinking agent and purification by washing of flotation, the deinking agent (I) comprises hydrogenated 24-50C dimeric acids with an iodine number \} 20 and/or their alkali(ne earth) metal and/or ammonium salts and/or alkoxylation products. Also claimed is the use of these acids and derivatives as (I) for deinking printed waste paper. Preferably (I) consists of 30-40C acids and/or alkoxylation products, especially a 36C acid with an iodine number \} 7.5. The waste paper is beaten in the presence of aqueous sodium hydroxide solution, water glass, hydrogen peroxide (H2O2) and optionally a ligand. Alternatively, beating and flotation are carried out at pH 6.5-8.8 in the absence of these additives and surfactants.
