VERFAHREN ZUM POLYMERISIEREN MITTELS UV-LICHT |
摘要 |
What is disclosed is a method for the free-radical polymerization, at a temperature between 0 DEG C. and 100 DEG 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. |
