|
Process
|
The starting foam is compressed, degassed, and combined/soaked
with a polyol in a nonbackmixing tubular reactor (e.g., plug-flow
reactor). Subsequently, the digestion is carried out via glycolysis-acidolysis approach.

|
Process
|
The PUFW is depolymerized
through two successive steps: (i)
reaction with a (di)carboxylic acid and a high-molecular-weight polyetherol
and (ii) the overall mixture is reacted again with a short-chain di
or triol. Acidolysis-glycolysis approach.
