  • To improve the poor mechanical and thermal properties of conventional PMMA bone cement, we impregnated three types of polyethylenes (PE) (200, 3,800, and 8,000 kg/mol). MMA/xylene solution was used to modify the surfaces of PEs and new composite PMMA bone cements were manufactured by impregnating 3 wt% of the surface-modified PEs into conventional PMMA bone cement. As molecuar weigth of PE increased, tensile strengths of the manufactured composite PMMA bone cements were improved. Also, we confirmed that the curing temperatures of the composite PMMA bone cements decreased from near $100^{\circ}C$ to $40^{\circ}C{\sim}80^{\circ}C$.
