Optimization of the phase separation problem of PBD in solution polymerization
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modifier or HIPS component, exhibited phase separation-related abnormalities during the solution polymerization process.
Cause Analysis
The gel content of PBD affects processing; improper temperature control leads to performance deterioration.
Solution
According to application requirements, control crosslinking density to systematically solve the problem.
Key Takeaway
The core of PBD processing lies in thermal-oxidative protection.
