PEOT/PBT multi-block copolymers are thermoplastic elastomers. A group of these multi-block copolymers are bioresorbable and also known as PolyActive.
The thermoplastic elastomeric properties of these multi-block copolymers are obtained by phase separation of the hydrophilic and hydrophobic segments in the polymers. Amongst other, this makes these block copolymers highly interesting for 3D printing. The polymers have a relatively low melting viscosity while after cooling very good mechanical properties result. The possibility to balance hydrophilicity/hydrophobicity of the surface makes these polymers much used for tissue engineering. The hydrophilic/hydrophobic phase separated morphology of these block copolymers is also a strong asset for the development and making of membranes with selective permeability properties.
We can fully customize PEOT/PBT multi-block copolymers to your requirements.
