Amine-terminated polysulfone sulfide, useful as epoxy curing agent |
| abstract |
Novel sulfur containing polyarylene polyether oligomers are disclosed. The oligomers are prepared through condensing salts of hydroxy and/or thio aromatic compounds, halobenzenoid compounds bearing two replaceable halogens and metal or ammonium sulfides following by end capping the resultant oligomer intermediate with a salt of a hydroxy and/or thio aromatic compound. |
