甲基丙烯酸甲酯(methyl methacrylate),简称MMA。主要用于制造各种MMA聚合物和共聚物。由于聚甲基丙烯酸甲酯具有透过紫外线、机械强度高、比重低等许多优点,近年来在国防各部门及其它国民经济中得到了广泛应用。本文仅从其毒性方面综述如下。对动物的毒性【急性毒性】MMA对兔的LD为6.5～7.4 g/kg;大鼠LD_(50)为8.4 g/kg,9.4 g/kg,10 ml/kg;豚鼠和狗LD_(50)分别为6.3 ml/kg
Methyl methacrylate (methyl methacrylate), referred to as MMA. Mainly used in the manufacture of various MMA polymers and copolymers. As polymethylmethacrylate has many advantages such as high UV transmittance, high mechanical strength and low specific gravity, it has been widely used in various national defense departments and other national economies in recent years. This article reviews only its toxicity as follows. Toxicity to animals 【Acute toxicity】 The LD of MMA in rabbits was 6.5-7.4 g / kg; the LD 50 of rats was 8.4 g / kg, 9.4 g / kg and 10 ml / kg respectively; Respectively 6.3 ml / kg
