ETHER POLYSULFIDES AND POLYETHER POLYSULFIDES, THEIR PREPARATION AND USE

摘要

Novel sulfur-containing compositions comprise a polyether polysulfide or an ether polysulfide. The polyether polysulfide may be based upon an alkoxylate (an alcohol or glycol-initiated compound) that is a copolymer of at least two of ethylene oxide, propylene oxide and butylene oxide. The polyether polysulfide may alternatively be based upon a homopolymer of ethylene oxide, propylene oxide or butylene oxide. The ether polysulfide may be based upon a methoxy-capped polyglycol or an alkyl ether of 1,3-dichloro-2-propanol.
