| Research Abstract |
Alginate is a biocompatible polymer that has high potential in medical uses such as vessels for drug delivery systems. However, for more specialized uses, the molecular weight needs to be controlled to around ~ 10^3 g/mol. In this work, we investigated the decomposition of alginate in high temperature high pressure water. Under the experimental conditions examined, the decomposition of alginate can be achieved to molecular weights above ~ 10^3g/mol in short reaction times (<1s)without any addition of catalysts, compared to conventional decomposition methods which require addition of acid or base catalyst and long reaction times (hours). Also, we found reaction condition dependencies in the monomer content of the product alginate.
