Abstract
A polyion complex prepared by reacting an alkali metal silicate with a nucleic acid base-containing polycation polymer having the unit formula: ##STR1## wherein X represents adenine, thymine, cytosine, uracil or a derivative thereof, in which the purine nucleus is bonded at 9-position and the pyrimidine nucleus is bonded at 1-position; M represents a vinyl monomer; x is 0 or a positive integer; B represents a halogen atom or hydroxyl group; y is 0 or 1; R represents a hydrogen atom or a C.sub.1-4 alkyl group; R.sub.1 and R.sub.2 respectively represents a C.sub.1-10 hydrocarbon group and n is an integer greater than 10.
