ABSTRACT:
A homopolymer of acrylic acid or methacrylic acid derivatives having the general formula: ##STR1## wherein R.sup.1 represents a hydrogen atom or methyl group; R.sup.2 is a residue of a compound having physiological activity; X is a residue of a compound having a hydroxyl group, amino group or carboxyl group at both ends in its chemical structure after bonding between such compound and acrylic or methacrylic acid, and between such compound and the physiologically active compound; and the homopolymer has a number-average molecular weight ranging from 20,000 to 200,000; and a process for the preparation thereof by a mechanochemical polymerization reaction; as well as a polymeric drug and prodrug comprising the homopolymer.
