Into a 500 ml four necked flask were charged 6 g of hydroxyapatite, 3 g of sodium chloride, 0.3 g of sodium lauryl sulfate and 330 g of pure water, and the mixture was added a mixture of 12.8 g of the same p-diethylaminoethylstyrene as prepared in Synthesis 1, 7.2 g of the same divinylbenzene as in Example 1, 20 g of acetophenone, 20 g of ethyl benzoate and 0.3 g of 2,2'-azobisisobutyronitrile under stirring. Then the mixture was stirred at 60° C. for 1 hour, at 70° C. for 2 hours and further at 80° C. for 4 hours. The copolymer in the form of particles thus obtained was thoroughly washed with water on a 300 mesh sieve and repeatedly washed with acetone using a glass filter. Then part of the copolymer was subjected to vacuum drying at 60° C. for 8 hours. The porous structure of the copolymer dried were measured by a mercury penetration porosimeter.
