Nitrogen-containing bisphenol compositions |
摘要 |
Bisamide and bisurethane bisphenols and bishaloformates are prepared by the reaction of amines with dicarboxylic acid halides or bisphenol bishaloformates. They are useful as intermediates for the preparation of cyclic heterocarbonates, which may in turn be converted to linear copolycarbonates.
