摘要：
The invention relates to a hardenable multi-part acrylic composition. The composition has at least two parts which react with each other upon being mixed together to progressively harden to form a solid cement, such as a bone cement. The beads in the first part comprise an acrylic bead polymer core produced by suspension polymerisation and having a Tg of ＞70℃ and emulsion polymerised acrylic microparticles at least partially coating the surface of the acrylic bead polymer core. The microparticles may form a porous coalesced network. The bone cement composition comprises the first part and a liquid second part and optionally, further parts. The parts are operable to form a cement which hardens to a solid mass upon mixing of the parts together. The composition further comprises an acrylic monomer component in the second part and an initiator component. A method of production of coated beads for the hardenable multipart composition and a solid cement is also described.本發明係關於一種可硬化多組份丙烯酸組成物。組成物具有至少兩種組份，其混合在一起後彼此反應以逐漸地硬化，從而形成固體黏合劑，諸如骨黏合劑。第一組份中的珠粒包含：丙烯酸珠粒聚合物核心，其藉由懸浮聚合產生，且Tg＞70℃；及乳液聚合之丙烯酸微粒，其至少部分地塗佈丙烯酸珠粒聚合物核心之表面。微粒可形成多孔聚結之網。骨黏合劑組成物包含第一組份及液體第二組份，且視情況包含其他組份。可操作組份以形成在將組份混合在一起後硬化成固體塊狀物之黏合劑。組成物進一步包含第二組份中之丙烯酸單體成分及引發劑成分。亦描述一種產生可硬化的多組份組成物及固體黏合劑之經塗佈珠粒之方法。
