    • A process for making silver nanostructures, includes the step of reacting at least one polyol and at least one silver compound that is capable of producing silver metal when reduced, in the presence of: (a) a source of chloride or bromide ions, and (b) at least one copolymer that comprises: (i) one or more first constitutional repeating units that each independently comprise at least one pendant saturated or unsaturated, five-, six-, or seven-membered, acylamino- or diacylamino-containing heterocylic ring moiety per constitutional repeating unit, and (ii) one or more second constitutional repeating units, each of which independently differs from the one or more first nonionic constitutional repeating units, and has a molecular weight of greater than or equal to about 500 grams per mole. A copolymer, useful as the at least one copolymer of the above described process comprises, based on 1000 constitutional repeating units of the copolymer: from 800 to 999 first constitutional repeating units, each independently comprising at least one pendant saturated or unsaturated, five-, six-, or seven-membered, acylamino- or diacylamino-containing heterocylic ring moiety per constitutional repeating unit, and from 1 to 200 second constitutional repeating units, each independently comprising at least one pendant organic moiety that comprises at least one primary, secondary, or tertiary amino nitrogen atom or quaternary nitrogen atom, and has a molecular weight of greater than or equal to about 500 grams per mole.
    • 一种制备银纳米结构的方法包括在以下存在下使至少一种多元醇与至少一种能够生成银金属的银化合物反应的步骤:(a)氯离子或溴离子源和( b)至少一种共聚物,其包含:(i)一个或多个第一组成重复单元,其各自独立地包含至少一个饱和或不饱和的,五,六或七元的含酰氨基或二酰氨基的杂环 每个构成重复单元的部分,和(ii)一个或多个第二结构重复单元,其每一个独立地不同于一个或多个第一非离子组成重复单元,并且具有大于或等于约500克/摩尔的分子量 。 可用作上述方法的至少一种共聚物的共聚物基于共聚物的1000个构成重复单元:800至999个第一组成重复单元,各自独立地包含至少一个饱和或不饱和的, 每个构型重复单元含有6-或7-元的含酰氨基或二酰基氨基的杂环环部分,以及1至200个第二构型重复单元,各自独立地包含至少一个侧链有机部分,其包含至少一个伯,仲, 或叔氨基氮原子或季氮原子,并且具有大于或等于约500克/摩尔的分子量。
