An acrylate based bone cement with well balanced low exotherm, low residual monomer, and high strength properties formulated from (1) a liquid component containing at least three different monomeric (meth)acrylates, e.g. a C₁-C₂ alkyl methacrylate, a straight or branched long chain (meth)acrylate having a molecular weight of at least 168, and a cyclic (meth)acrylate having a molecular weight of at least 168, and (2) a polymer powder component containing (meth)acrylate polymers or copolymers. The final bone cement may also contain conventional additives such as polymerization inhibitors, activators, crosslinkers, X-ray contrast material, polymerization initiators, antibiotics, antiseptics, and the like.
一种丙烯酸酯基骨水泥,具有平衡良好的低放热、低残留单体和高强度特性,由 (1) 一种液体组分配制而成,该组分含有至少三种不同的(甲基)丙烯酸酯单体,例如C₁-C₂甲基丙烯酸烷基酯、分子量至少为 168 的直链或支链长链(甲基)丙烯酸酯和分子量至少为 168 的环状(甲基)丙烯酸酯,以及 (2) 含(甲基)丙烯酸酯聚合物或共聚物的聚合物粉末成分。最终的骨水泥还可能含有常规添加剂,如聚合抑制剂、活化剂、交联剂、X 射线造影剂、聚合引发剂、抗生素、防腐剂等。
