Abstract

1508511 Polyoxyethylene dihalides GAF CORP 13 Jan 1976 [5 June 1975] 01263/76 Heading C2C [Also in Division C3] Mixtures of polyoxyethylene dihalides comprises components each of which corresponds to the general formula XCH 2 CH 2 (OCH 2 CH 2 ) n OCH 2 CH 2 X (I) in which n is 3-600, x is halogen and the mixture has an average molecular weight of 275- 30,000. X is preferably Cl or Br. I may be prepared by reacting thionyl chloride with polyethylene glycols.
