Dianhydrohexitol monomeric chain integration: RoquetteRecent Research Landscape

Petroleum-based polyester backbones lack the thermal stability and rigidity required for high-performance packaging, which is mitigated by integrating bio-based rigid diols. This substitution increases the glass transition temperature to prevent structural deformation under heat.

What technical problems is Roquette addressing in Dianhydrohexitol monomeric chain integration?

Petrochemical monomer dependency

(17)evidences

High melt viscosity and thermal degradation during processing limit the utility of bio-based rigid monomers. Improving these properties prevents material failure and enables the replacement of petroleum-based plasticizers.

Thermal and mechanical brittleness

(8)evidences

Bio-based dianhydrohexitol polyesters suffer from insufficient molecular weight and poor mechanical toughness. Overcoming these limitations allows for structural applications and industrial melt processing.
