    • Polyglycolate compounds are provided having the general structure: ##STR1## wherein n is an integer from 2 to about 10; R is C.sub.1-20 linear or branched alkyl, alkoxylated alkyl, cycloalkyl, aryl, alkylaryl, substituted aryl; R' and R" are independently H, C.sub.1-20 alkyl, aryl, C.sub.1-20 alkylaryl, substituted aryl, and NR.sub.3.sup..alpha.+, wherein R.sup..alpha. is C.sub.1-30 alkyl; and L is a leaving group displaceable in a peroxygen bleaching solution by perhydroxide anion. When this compound is combined with a source of peroxygen in aqueous solution, then a plurality of stain removing peracids are formed. Such peracids are formed substantially sequentially beginning with the carbonyl adjacent to the leaving group L. Thus, a first stain removing peracid having the structure ##STR2## will be formed in amounts approaching quantitative yield.
    • 提供了具有以下通用结构的聚乙醇酸酯化合物:其中n为2至约10的整数; R为C 1-20直链或支链烷基,烷氧基化烷基,环烷基,芳基,烷基芳基,取代芳基; R'和R“独立地为H,C 1-20烷基,芳基,C 1-20烷基芳基,取代的芳基和NR 3α+,其中Rα为C 1-30烷基; L是在过氧漂白溶液中通过全氢氧化物阴离子置换的离去基团。 当该化合物与水溶液中的过氧源组合时,形成多个去污过酸。 这样的过酸基本上是从与离去基团L相邻的羰基开始形成的。因此,具有接近定量收率的量的第一种去除污垢的过酸的结构将形成。
