A medical resin composition is produced by mixing a powder of a polymer (A) comprising repeating units having an ester group and a liquid of a vinyl ester monomer (B) having 6 or more carbon atoms to increase a viscosity and, according to demand, further performing a polymerization reaction. The thus produced resin composition inhibits leaching of irritative substances, reduces any adverse effects on the human body by endocrine disruptors, etc. and can be prepared with high operational efficiency. The resin composition is suitably used as a dental resin composition such as a tissue conditioner, a functional impression material, a lining material, a denture base material or a mouth piece material.
一种医用树脂组合物的制备方法,包括将含有酯基重复单元的聚合物(A)粉末和含有6个或更多碳原子的乙烯酸酯单体(B)液体混合以增加粘度,并根据需要进一步进行聚合反应。由此制得的树脂组合物抑制刺激性物质的渗出,减少内分泌干扰物对人体的不良影响等,并且可以高效制备。该树脂组合物适用于牙科树脂组合物,例如组织调整剂、功能印模材料、填补材料、义齿基材料或口腔器材材料。
