摘要: A segmented copolymer can be produced without needing a chain extender. The conventional view that extender was needed to construct segmnented has been disproven. For example, by certain reactions of diisocyanate with oligomeric and polymeric diols or diamines, copolymers Segmented not containing ethylene glycol, 1,4-butanediol diamine produced.
