　　It is increasingly recognised that properties of polymers and polymer composites depend on the structure imparted during processing,which we termprocess structuring.Solid phase orientation processing at temperatures between Tg and the melting point provides a most striking example of process structuring,in terms of the magnitude of property changes which can be achieved—e.g.,several hundred percent enhancements in physical properties.Molecular orientations and large scale effective morphological reorganisations achieved by drawing or other forming processes can be locked into the final product,which remain stable in final products.The products can be used for significant load bearing applications,or orientation may be intentionally recoverable in a controlled manner,forshape memoryproducts.Remarkable cost-effective improvements in properties can consequently be achieved in many polymers and polymer composites by solid phase orientation processing,with applications including medical technology (e.g.tissue fixations,stents,drug eluting implants),construction (the spin-out at www.eovationsllc.com),high performance pipes,and personal products.
