Coace® KS-05 is a random styrene-acrylonitrile-glycidyl methacrylate terpolymer.
The random styrene-acrylonitrile-glycidyl methacrylate (SAN-GMA) terpolymer is an excellent compatibilizer for the PLA/PBAT alloy. The terpolymer structure's unusual combination of functional groups allows it to develop strong contacts with both the PLA and PBAT phases, facilitating compatibility and improving the performance of the resultant alloy.
The SAN-GMA terpolymer's efficacy as a compatibilizer is based on its capacity to form strong interfacial adhesion between the PLA and PBAT phases. The glycidyl methacrylate (GMA) groups in the terpolymer can establish covalent connections with the hydroxyl groups in the PLA, whilst the styrene and acrylonitrile (SAN) segments can interact with the PBAT phase. This multifunctional compatibility mechanism creates a robust and stable interface, allowing for effective stress transmission and better overall performance of the PLA/PBAT alloy.
1. Enhanced mechanical properties: The improved interfacial adhesion achieved by using the SAN-GMA terpolymer compatibilizer results in considerable improvements in the mechanical characteristics of the PLA/PBAT alloy
2. Tensile Strength: Improved compatibility between the PLA and PBAT phases results in increased tensile strength, allowing for the development of stronger and more lasting PLA/PBAT-based components.
3. Impact Resistance: The compatibilizing effect of the SAN-GMA terpolymer improves the impact resistance of the PLA/PBAT alloy, making it more appropriate for applications where impact resistance is crucial.
4. Elongation at Break: The SAN-GMA terpolymer efficiently bridges the gap between PLA's intrinsic brittleness and PBAT's flexibility, yielding a PLA/PBAT alloy with higher elongation at break and overall ductility.
5. Improved Thermal and Processability: The SAN-GMA terpolymer compatibilizer not only improves the mechanical qualities of the PLA/PBAT alloy, but it also improves its thermal and processing properties.
6. Thermal Stability: The SAN-GMA terpolymer's compatibility-enhancing action can improve the thermal stability of the PLA/PBAT alloy, allowing for a wider temperature range for safe and dependable operation.
7. Melt Viscosity: The compatibilizing activity of the SAN-GMA terpolymer can help optimize the PLA/PBAT alloy's melt viscosity, resulting in increased processability and easier integration into diverse production processes.
8. Dimensional Stability: The increased interfacial adhesion promoted by the SAN-GMA terpolymer can contribute to improved dimensional stability of the PLA/PBAT alloy, lowering the likelihood of warpage or deformation during processing and usage.
9. Diverse Application Potential: The adaptability of the PLA/PBAT alloy, along with the performance-enhancing characteristics of the SAN-GMA terpolymer compatibilizer, opens up a wide range of application possibilities.
