  A depolymerized-carboxyalkyl polysaccharide formed by de polymerizing a polysaccharide having from 0.5 to 3.0 degrees of substitution and reducing the molecular weight of said polysaccharide before or after said depolymerizing provides a biodegradable scale inhibitor useful to prevent deposition of scale comprising, for example, calcium, barium, sulfate and salts thereof. The depolymerized carboxyalkyl polysaccharide is particularly useful in off shore oil production squeeze treatments and in the treatment of scale formed in industrial water treatment.

  通过将具有0.5至3.0度取代度的多糖聚合物去聚合并在去聚合之前或之后降低该多糖聚合物的分子量，形成一种脱聚合羧烷基多糖，可提供一种可生物降解的阻垢剂，用于防止垢的沉积，包括钙、钡、硫酸盐及其盐。脱聚合羧烷基多糖在海上油田生产挤压处理和工业水处理中形成的垢的处理中特别有用。
