Optimization of the gel problem of PBD in solution polymerization
Problembeschreibung
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited gel-related abnormalities during the solution polymerization process.
Ursachenanalyse
The molecular weight distribution of PBD affects processing; improper shear control leads to performance deterioration.
Lösung
According to application requirements, add anti-aging agent to systematically solve the problem.
Wichtigste Erkenntnis
The core of PBD processing lies in thermal-oxidative protection.
