  Polysaccharide aldehydes having the formula Sacch-O-CH2-CH = CH-CHO, such as starch, cellulose, and gum aldehydes, are useful for imparting wet, dry, or temporary wet strength to paper. They are prepared by a non-oxidative method which involves reacting the polysaccaride base, in the presence of alkali, with a derivatizing acetal reagent and then hydrolyzing the acetal by adjusting the pH to less than 7. In the formulas, n is 1-3; R" and R'2 are independently an alkyl, aryl, aralkyl, or alkaryl group when n is 1, R" or R'2 is one of the groups when n is 2, or R" and R12 are not present when n is 3; R13 is an alkyl group or an aralkyl group; R14 and R15 are individually a hydrogen or a methyl group; R16, R", and R18 are individually an alkyl group; y- is an anion; and A and A' are lower alkyls or together form at least a 5-membered cyclic acetal.

  具有 Sacch-O-CH2-CH = CH-CHO 式的多糖醛、 如淀粉、纤维素和树胶醛，可用于赋予纸张湿强度、干强度或临时湿强度。它们是通过非氧化法制备的，即在碱存在的情况下，使聚羧酸基与衍生缩醛试剂反应，然后通过调节 pH 值至 7 以下使缩醛水解。在配方中，n 为 1-3；当 n 为 1 时，R "和 R'2 独立地为烷基、芳基、芳烷基或烷芳基，当 n 为 2 时，R "或 R'2 为其中一个基团，或当 n 为 3 时，R "和 R12 不存在；R13 为烷基或芳烷基；R14 和 R15 分别是氢或甲基；R16、R "和 R18 分别是烷基；y- 是阴离子；以及 A 和 A'是低级烷基或共同形成至少 5 元环缩醛。

  Polysaccharide graft polymers which comprise an acetal-containing or aldehyde-containing homopolymer or copolymer grafted to a polysaccharide base, represented as Sacch-g-(M')x or Sacch-g-(M)y (M')z and Sacch-g-(M")x or Sacch-g-(M)y-(M")z, have been prepared. M' and M" respectively represent repeating units derived from one or more ethylenically or allylically unsaturated monomers containing an acetal group or aldehyde group; M represents a repeating unit derived from one or more ethylenically or allylically unsaturated monomers other than the acetal-containing or aldehyde-containing monomer; x is at least 2 and y and z are at least 1; A and A' are independently a lower alkyl or A and A' together form at least a 5-membered cyclic acetal; with the proviso that the graft polymer contain no -groups when the aldehyde groups are present. The aldehyde-containing graft polymers are useful for imparting wet strength to paper. Various novel acetal-and aldehyde-containing monomers have also been prepared they can be graft polymerized to polysaccharide substrates or polymerized by conventional emulsion polymerization techniques with vinyl polymerizable monomers.

  多糖接枝聚合物由接枝到多糖基上的含缩醛或含醛均聚物或共聚物组成，已制备出 Sacch-g-(M')x 或 Sacch-g-(M)y (M')z 和 Sacch-g-(M")x 或 Sacch-g-(M)y-(M")z。M' 和 M "分别代表由一种或多种含缩醛基团或醛基团的乙烯基或烯丙基不饱和单体衍生的重复单元；M 代表由一种或多种含缩醛基团或醛基团单体以外的乙烯基或烯丙基不饱和单体衍生的重复单元；x 至少为 2，y 和 z 至少为 1； A 和 A'独立地为低级烷基，或 A 和 A'共同形成至少 5 元环状缩醛；但接枝聚合物在含醛单体时不含有-基团。 当存在醛基时，接枝聚合物不包含-基团。含醛接枝聚合物可用于提高纸张的湿强度。此外，还制备出了各种新型的含缩醛和醛单体，它们可以接枝聚合到多糖基材上，或通过传统的乳液聚合技术与乙烯基可聚合单体聚合。
