Polyalkyleneamine polyester dispersant chemistry: BASFRecent Research Landscape
Poor silica stability in polymer matrices leads to mechanical failure and processing bottlenecks. These innovations utilize specific block copolymer and polyester-amine architectures to stabilize particle dispersions and prevent agglomeration.
What technical problems is BASF addressing in Polyalkyleneamine polyester dispersant chemistry?
Particle agglomeration and sedimentation
(8)evidences
Inadequate stabilization of silica and aromatic particles leads to sedimentation and poor flow properties. Overcoming these forces ensures uniform distribution and long-term suspension stability.
Unstable mineral suspension viscosity
(6)evidences
Inadequate light scattering and coverage in aqueous systems. Enhancing opacity ensures visual consistency and reduces material consumption in coatings.
Irreversible particle agglomeration during drying
(3)evidences
Polymer dispersions tend to fuse or clump permanently when water is removed during spray drying. Preventing this loss of dispersibility ensures the powder can return to its original primary particle size upon rehydration.
