| titleOfInvention | Process for the chloro-sulphonation of polyethylene |
| abstract | Polyethylene of particle size not greater than 0.25 mm. is chlorosulphonated, in the absence of a solvent or other liquid phase, by treatment with a gaseous mixture of chlorine and sulphur dioxide, optionally containing an inert gas, at a temperature not above 100 DEG C. Treatment with gaseous chloride before and/or after the chlorosulphonation is also included. The process of the invention may be operated in the presence of actinic light, e.g. ultraviolet light, and may be effected in shelved reactors, rotary drums, kneading machines, or screw-conveyers, or by a fluidized bed process. The polyethylene used may be of high molecular weight as obtained by the use of catalyst complexes derived from titanium tetrachloride, zirconium and thorium acetyl acetonates, aluminium triethyl, and diethyl- and diisobutyl-aluminium chlorides. In Example (1) the high molecular weight polyethylene used is obtained in a C7-C10 hydrocarbon medium and is purified by the use of steam. |
