Orthopaedic structures, and processes for making the same, are provided in which the orthopaedic structure comprises a polymeric material which contains a block copolymer having grafted to it styrene, an alkyl acrylate and optionally methyl methacrylate. The orthopaedic structures are substantially transparent, formable and reformable at temperatures of about 45.degree. to about 65.degree. C. and are essentially rigid at ambient temperatures.

Orthopaedic structures from polymeric materials

A thermoplastic polymer comprising a styrenic monomer, an acrylate, a methacrylate and a block copolymer is provided which possesses an unexpected excellent balance of properties including good physical properties, good elongation and a high degree of transparency. Also provided are processes for the preparation of the thermoplastic polymer.
