    • Disclosed are novel carbonate block copolymers and methods of making the same. Some carbonate block copolymers include oligomeric carbonate blocks bonded to one or more silicon-containing non-carbonate block, wherein the silicon-containing non-carbonate block is comprised of a diamine moiety and the carbonate block is joined to the silicon-containing non-carbonate block through a urethane group. Other carbonate block copolymers include oligomeric carbonate blocks bonded to one or more non-silicon-containing non-carbonate block, wherein the non-silicon-containing non-carbonate block is comprised of a diamine moiety and the carbonate block is joined to the non-silicon-containing non-carbonate block through a urethane group. The carbonate block may include Bisphenol-A moieties. The diamine from which either the silicon-containing or non-silicon-containing non-carbonate block is derived may be primary, secondary or tertiary.
    • 公开了新型碳酸酯嵌段共聚物及其制备方法。 一些碳酸酯嵌段共聚物包括与一个或多个含硅非碳酸酯嵌段键合的低聚碳酸酯嵌段,其中含硅非碳酸酯嵌段由二胺部分组成,碳酸酯嵌段连接到含硅非碳酸酯 通过氨基甲酸酯基团阻断。 其它碳酸酯嵌段共聚物包括与一个或多个非含硅非碳酸酯嵌段键合的低聚碳酸酯嵌段,其中非含硅非碳酸酯嵌段由二胺部分组成, 含硅非碳酸酯嵌段通过氨基甲酸酯基团。 碳酸酯嵌段可以包括双酚A部分。 得自含硅或非含硅非碳酸酯嵌段的二胺可以是伯,仲或叔。
