Controllable Degradation polycarboxylic acid copolymer - organic calcium / bone implant filled composites, and preparation of phosphonium salt

Controllable Degradation polycarboxylic acid copolymer - organic calcium / phosphorus salts filled composite bone implant and method of preparation. The composite bone implant and a polycarboxylic acid copolymer medicine acceptable organic calcium / phosphorus salts of the chemical composition, the organic calcium / phosphorus salt is 20 to 90% of the total mass of composite material; copolymer polyols by amino acid e- aminocaproic acid with at least two other amino acid polymerization, e- aminocaproic acid, wherein the amino acid copolymer is at least 50% of the total molar amount, the amount of each of the other amino acids, amino acid copolymers, respectively, is at least 0.5% of the total molar amount of . The composite bone implant more suitable for the body's natural bone repair healing period, the soaking solution pH value between 6.5 and 7.5 after degradation, little effect on the local physiological environment, will not cause irritation, and is conducive to the growth of tissue cells repair.
