    Abstract: PURPOSE: To obtain a material for implant having satisfactory compatibility and reproductivity of mechanical strength by containing respective specified amounts of thermally convertible intermediate phases, polymer, apatite and a fibrous or powdery filler as essential components. CONSTITUTION: This material for implant contains, as essential components, (A) 30-95wt.% of thermally convertible intermediate phase polymer, (B) 5-70wt.% of apatite and (C) 0-60wt.% of a fibrous or powdery filler different from (B). The thermal convertible middle phase polymer has anisotropic molten phase to be detected easily by using a polarized microscopy. Between crossed polarizers, the molten polymer with a thickness of 10μm clampled between glass plates shows a pattern due to the intermediate phase. In order to obtain an anisotropic molten phase, the main chain is necessary to have a certain linearity which can be attained by adjusting a proportion of monomer amounts suitably. Anisotropy of the molten phase and orientation of the relative polymer molecules increase strength and rigidity of a product made from the polymer eminently.
