Optimization of PBD phase separation Problem in Emulsion Polymerization
Problem Phenomenon
Polybutadiene PBD, as an elastomer toughening modification or HIPS component, exhibits phase separation-related abnormalities during the emulsion polymerization process.
Cause Analysis
The Mooney viscosity of PBD affects processing; improper crosslinking control leads to performance deterioration.
Solution
Add antioxidant according to application requirements to solve systematically.
Key Takeaway
The core of PBD processing lies in the crosslinking/shear balance.
