Abstract: A hard tissue repair adhesive composition and a hard tissue repair kit comprising same. The adhesive composition comprises a polymerizable monomer (A), polymer powder (B), a polymerization initiator (C), and a filler (D). The polymerization initiator (C) comprises 100 parts by weight of alkoxydialkylboron having a purity of 97% or more and 0.2-5 parts by weight of an alcohol having a boiling point of 60° C. to 180° C. The polymerization initiator (C) does not generate smoke or coking or present ignition quality even when in contact with paper, porous fibers or the like in air, is easy to be taken in a small amount, and can provide a polymerizable composition with high polymerization activity, thereby providing an adhesive composition suitable for hard tissue repair. (A), (B), (C), (D) and all other components comprised according to requirements of the adhesive composition for hard tissue repair can be separately or mixedly stored in three or more members to form a repair kit.

Abstract: An adhesive composition for hard tissue repair, comprising a polymerizable monomer (A), a polymer powder (B), and a polymerization initiator (C), wherein the polymerization initiator (C) is represented by the following general formula: [CH3(CH2)m-]2B—O(CH2)nCH3, and in the formula, m and n are each independently an integer from 1 to 4, and the relational expression that 2m+n<=10 is satisfied. The polymerization initiator cannot show coking or ignitability even when in contact with paper, a porous fiber, and the like in air, and is high in fluidity and easy to take a small and correct amount, so as to reduce adverse effects on a human body: and high polymerization activity can be given to a polymerizable composition, so that the polymerizable composition is cured within a short time, and the adhesive composition suitable for hard tissue repair is provided.
