通常,从单体获得聚合体的聚合反应,是在室温以上的较高温度下进行的。温度低了,不能加速聚合反应的进行;温度过高,会减小聚合物的分子量。所以,在聚合反应中,必须适当地控制温度。那末,在室温以下的温度,甚至在零下几十度的低温下,是否能发生引发聚合呢?答案是肯定的。七十年代,在国外,发展了一种过冷态的聚合反应。在很低的温度下,单体成高粘度的液相,聚合反应可以极迅速地进行,聚合物制品有着特殊的性能。因此,这种新的聚合方法的问世,十分引人瞩目。有合适的玻璃化性单体体系、有适当的低温环境 In general, the polymerization of the polymer from the monomer is carried out at a higher temperature than room temperature. Low temperature, can not speed up the polymerization reaction; temperature is too high, will reduce the molecular weight of the polymer. Therefore, in the polymerization reaction, the temperature must be properly controlled. Then, at room temperature below the temperature, even at a low temperature of minus tens of degrees, can trigger polymerization? The answer is yes. Seventies, abroad, the development of a supercooled polymerization. At very low temperatures, the monomer becomes a highly viscous liquid phase, polymerization can proceed very rapidly and the polymer product has special properties. Therefore, the advent of this new method of aggregation, very interesting. A suitable vitrification monomer system, there is a suitable low-temperature environment
