Under the action of catalyst and low molecular weight alcohol, polyurethane degraded to low
molecular weight liquid at a certain temperature. Choosing the right reagent and degradation condition
can get high quality polyol, not only with low reaction temperature and short reaction time, but also with
higher degradation efficiency. The most important detail is products without complex subsequent
handling. It can be used directly as the raw material to preparation of polyurethane products . At
present, people generally accepted the reaction mechanism that carbonates was ruptured, replaced with
short of alcohol chain, and releasing the long chain polyol and aromatic compounds.
