20世纪40年代初,美国通用电气公司发明了热硫化硅橡胶。尽管热硫化硅橡胶生胶有很多品种,但只有2种工业生产方法。一种是低分子量环体的开环聚合,另一种是端羟基线形低聚物的脱水缩合。后者只有德国的瓦克公司曾采用过,现在全世界都只用开环聚合这一种方法采生产热硫化硅橡胶生
In the early 1940s, the United States General Electric Company invented thermal vulcanized silicone rubber. Although heat vulcanized silicone rubber has many varieties, but only two kinds of industrial production methods. One is the ring-opening polymerization of a low molecular weight ring and the other is the dehydration condensation of a linear hydroxyl-terminated oligomer. The latter was only used by Wacker in Germany. Now the world only uses open ring polymerization to produce heat-vulcanized silicone rubber
