Amorphous and semicrystalline copolyamide blends: BASFRecent Research Landscape

Standard polyamides lack the flexibility and barrier properties required for high-performance films, leading to mechanical failure or permeability issues. Integrating ether-functionalized diamines and dimer acids into the polymer backbone engineers specific crystallinity and ductility to prevent film rupture.

What technical problems is BASF addressing in Amorphous and semicrystalline copolyamide blends?

Insufficient gas barrier performance

(15)evidences

Incompatible polymer phases in multilayer structures lead to delamination and mechanical weakness. Improving bond strength between layers ensures structural integrity in high-pressure fluid transport.

Inadequate multilayer film flexibility

(5)evidences

Standard polyamides suffer from brittleness and poor impact resistance in thin film applications. Incorporating dimer acids and ether-linked diamines addresses the mechanical failure and lack of elasticity inherent in rigid crystalline structures.
