    • What is disclosed is a method for the free-radical polymerization, at a temperature between 0.degree. C. and 100.degree. C. using ultraviolet light, of a material to be polymerized which comprises at least one unsaturated monomer, which method comprises adding an ultraviolet absorber which is only weakly effective or is inert as a free-radical initiator to the material to be polymerized, initiating polymerization of the material in an initiation phase by irradiation thereof with ultraviolet light, controlling the further course of the polymerization in a polymerization phase by increasing the intensity of the irradiating ultraviolet light with time, and concluding the polymerization by irradiation with ultraviolet light in a terminal phase, said ultraviolet absorber absorbing in the wavelength region of the irradiating ultraviolet light.
    • 所公开的是在0℃至100℃的温度下使用紫外光进行自由基聚合的待聚合材料包括至少一种不饱和单体的方法,该方法包括加入紫外线 吸收剂,其仅对于待聚合的材料是弱有效的或作为自由基引发剂是惰性的,通过用紫外光照射引发材料在引发阶段的聚合,通过在聚合阶段中控制聚合阶段的进一步的聚合过程 随着时间的推移增加照射紫外线的强度,并且通过在末端相中照射紫外光来结束聚合,所述紫外线吸收剂在照射紫外线的波长区域中吸收。
