| Abstract: | Polymeric calcium phosphate cement is a new type of bioactive materials used in bone prostheses. In the study the cement was derived from mixing copolymer of acrylic acid and itaconic acid with the powder of calcium phosphate. The compressive strength of the cement is enhanced up to 42 MPa after surface modification of TTCP-like powder by MMA. Its initial setting time is 4.5 min and final setting time is 8.5 min.For the cement by powder mixture of α-TCP and TTCP-like, its compressive strength reaches 43 MPa, its initial setting time is 5.5 min and its final setting time is 11.0 min. |

| Keywords: | polymeric calcium phosphate cement implant materials of bone setting time compressive strength preparation property |
